1. Introduction The CP 440 combines the high accuracy of digital electronics with the convenience and ease of use of an analog test gauge. Accurate to ± 0.05% FS, the CP 440 can be used as a calibration reference, or in any application where high accuracy pressure measurement is required. Many user configurable functions have been designed into the CP 440 in- cluding sampling rate, TARE, damping, auto shut off, and min-max. Once the gauge is configured, settings can be locked and password protected to prevent unauthorized changes to configuration. Unpacking: Check to see that your CP 440 has arrived intact. Batteries are factory installed unless you have purchased the optional 24V powered version, in which case batteries are not supplied or installed. 1.1 CP 440 Display and Controls Turns Power on/off Enters set-up and Pressure display configuration menus Engineering Units Zeros the display, 0 - 00% bar graph Scrolls forward through menu displays Recalls min and max Selects an action in readings.

2. Operation Power: The standard CP 440 is supplied with 3 AA batteries installed. If you purchased the optional 24Volt powered version, batteries are not installed. Connect a 24V power supply to the terminal block on the rear of the gauge, noting proper polarity. Do not install batteries when external power will be used. Push the power button momentarily to turn the unit on. Push it again to turn it off. 2.1 Set-up and configuration: Push the CONFIG button to access the user-settable functions on the gauge. Each time the CONFIG button is pressed; the display advances to the next function. Once a function has been set, press ENTER to exit the configuration menu, or CONFIG to continue with further configuration. In order, the configuration menu and operation is as follows: . E ngineering Units set. The unit is shipped configured to display Psi. By pressing the 6 and 5 (ZERO and MAX/MIN) keys you can scroll forward and backwards through the 8 standard engineering units plus a one custom unit/scale. When the desired unit is displayed, press ENTER or CONFIG. Pressure will now be displayed in the chosen engineering units. See the Specifications section of this manual for a list of available engineering units. See the Supervisory Mode section for details on setting up custom units. 2. S et Auto Off. The auto-shut off can be set in minute increments from to 30 minutes or “off” (continuous operation). The unit is shipped set for 30 minutes. Use the 6 and 5 keys to set the desired interval. The “off” setting is at the low end of the choices, below minute. 3. D isplay battery voltage. Actual voltage and a percent of life bargraph indicate battery condition... -

4. D isplay actual temperature. The CP 440 is temperature compensated, this displays the temperature measured by the internal sensor. The value can be set to degrees F or degrees C using the arrow keys. 5. S et damping. Choices are “on” and “off” set with the 6 and 5 keys. Turning damping on will smooth readings from pulsating pressure sources. 6. Set sample rate: This determines how often pressure is sampled and the display is updated. Choices are 0.5, , 3, and 0 samples/second. Note that 0/sec provides the fastest response time. 7. S et TARE. This allows you to set a constant offset value, which is then subtracted from the measured pressure. For example if a TARE is set at 30 Psi, and the measured pressure is 37 Psi, the displayed value will be 7 Psi. A pressure of 27 Psi would be displayed as –3 Psi. The tare value is set manually with the 6 and 5 keys, and is based on the engineering units and resolution selected for display. TARE value can be set to the maximum range of the gauge. The bar graph will always display the actual pressure based on the full range of the gauge regardless of the tare setting. This is done for safe- ty to insure that even with a “0” reading that pressure is being applied to the gauge. 8. F unction Lock: Access to each of the settable parameters above can be turned “off” once set, to prevent unauthorized changes to configu- ration. This is accomplished through a password protected “superviso- ry mode”. Press ENTER to access the supervisory mode, or CONFIG to return to normal operation. 3. Supervisory Mode Press ENTER when “FUnC LOCK” is displayed, 0PWRD will be displayed on the gauge. The password to enter supervisory mode is 0, set using the 6 and 5keys. Holding a key continuously will cause the display to advance more quickly for faster setting. The password is factory set and cannot be changed. - Page 6 . Y our CP 440 is shipped from the factory with all setting access “unlocked” or available to be changed. 2. I n supervisory mode each of the parameters can be locked or unlo- cked using the 6 and 5 keys. Select LOC (lock) for those parameters you do not want to be accessible, and UnLOC (unlock) for those can be accessed. 3. In order, the functions that can be unlocked, locked or accessed are: • Zero function (enable/disable) • Set pressure units (enable/disable) • Auto shutdown adjustment (enable/disable) • Damping settings (enable/disable) • Sample rate setting (enable/disable) • Tare setting (enable/disable) • Custom engineering units (set scale factor) 4. U se the CONFIG key to scroll through the above choices, and the 6 and 5 keys to lock and unlock features. Press CONFIG to continue scrolling through the parameters, pressing ENTER at any point saves your settings and returns the gauge to normal operation. When a function is “locked, it cannot be accessed or changed from its current state. To change a locked function, enter the supervisory mode, and unlock the function. Once it is changed, you may enter superviso- ry mode to lock access again. 5. S etting a custom engineering unit or scale: The last menu choice in supervisory mode is SET FACTR. This allows you to set a multiplier factor from 0.00 to 00, creating a custom scale. The set factor will be multiplied by the Psi measured, the result will be displayed. For example: 40 Psi is the equivalent of 000 g of product in a tank. You want to display the product weight , using a 00 Psi gauge. By setting a factor of 25, a 40 Psi pressure would display as 000 (40 x 25). The engineering unit displayed on the CP 440 will be “Cust”.

4. Normal Operation Turning the backlight on and off: Press the ENTER button. Zeroing the display: Press and hold the ZERO button. MAX/MIN: The CP 440 stores minimum and maximum pressure values in memory. Pressing the MAX/MIN button once will display the minimum pressure from memory. Pressing the MAX/MIN button again will display the maximum pressure from memory. After about 2 seconds, the gauge returns to normal (live display) operation. To clear the MAX/MIN memory registers, press and hold the MAX/MIN button for 2 or more seconds until “CLr” is displayed. The analog bar graph at the bottom of the display indicates the applied pressure level relative to the full range of the gauge. Keep in mind that if a TARE value has been programmed into the gauge, the displayed pressure will not reflect the true pressure applied. Changing the Batteries Grasp the face ring on the CP 440, turn it approximately ⁄4 turn coun- terclockwise and remove. The face of the gauge can now be lifted to expose the battery holder. Install three AA batteries noting proper polarity. Reassemble the case making certain that the face is properly oriented. If you purchased the optional 24 Volt powered version, the terminals for power input are located on the rear of the gauge. To apply power simply connect 24 volts to the rear terminal block taking care to observe proper polarity. WARNING Gauges ordered with the external power option will not come with batteries installed. Batteries MUST NOT be installed when operating on external power. Battery life Battery life is about 500 hours (60 days) of continuous use with the backlight off. With intermittent use, batteries could last a year or more. There is a low battery icon in the upper left of the display. It will appear when battery level is low. Replace batteries per recommendations found in the specifications section of this manual. -

Appendix 1: CP 440 Calibration Procedure Overview Calibration adjustment of the CP 440 is performed electronically ´ v ia inter- nal software with the case closed. There are no mechanical adjustments; all calibration commands and adjustments are done via the keypad, using the display to guide the user through the calibration process. Eight calibration points are used in the adjustment program, working from full scale to zero at pressures equaling 00%, 87.5%, 75%, 62.5%, 50%, 37.5%, 25%, 2.5%, and 0% of full scale plus vacuum. Note: This is an ambient temperature calibration, and should be perfor- med at an ambient temperature of 23°C ± 3°C (72° F ± 5° F). Calibration outside this temperature range will invalidate the temperature compensa- tion program in the CP 440. - Page 10 Calibration Interval You should check performance of the unit at the interval required by your calibration program. We recommend adjustment when measurement deviates by more than 75% of the specified accuracy, or 0.04% Test Equipment Verification and calibration of the CP 440 requires pressure and/or vacu- um standards able to produce and indicate pressures from vacuum to the full-scale range of the unit under test. In order to maintain the specified accuracy of the CP 440, standards should have a TUR of 4: or better. Connections: The PI uses a /4 NPT male connection in the pressure input port. Various adapters may or may not be needed to connect to the pressure standard. Always make sure the hose, tubing, and fittings etc have a rated working pressure at or above the pressure of the unit. Also it is important that there be no leaks when performing calibration; use Teflon tape where appropriate. Entering Calibration Mode: After you have made your connections, turn the power on while holding the CONFIG key. Use the arrow keys to enter the password. The pass- word is 0. If you have entered calibration mode correctly the display should look as shown below. The pressure value displayed will be the full-scale value of the gauge. Procedure: Screens shown in this manual represent the displays shown with a 500 psi Gauge. The CP 440 will prompt the technician for the appropriate pressure at each calibration point. 500.00 CAL MODE Use the Pressure Standard to output 500.00 psi (00%).
