Page 15: Programmable Set-Points
Dry-Well Controller Operation Programmable Set-points The controller stores 8 set-point temperatures in memory. The set-points can be quickly recalled to conveniently set the Product to a previously-programmed temperature set-point. To set the temperature, first select the set-point memory. Push SET from the temperature display function to access this function. -
Page 16: Scan
9103 User’s Guide Scan Set and enable the scan rate so that when the set-point is changed the calibrator heats or cools at a specified rate (degrees per minute) until it reaches the new set-point. With the scan disabled, the calibrator heats or cools at the maximum possible rate. -

Dry-Well Controller Operation Enable the Hold Temperature Display Push UP when the temperature shows to enable the Hold Temperature Display feature. The Hold Temperature Display shows the hold temperature on the right and the switch status on the left. The status c means the switch is closed and o means the switch is open. -

9103 User’s Guide To set up the test: 1. Connect the switch wires to the terminals on the front of the Product and place the switch in the well. 2. Enable set-point scanning by setting the scan to ON in the primary menu (see Scan Control). -
Page 19: Proportional Band
Dry-Well Controller Operation Proportional Band In a proportional controller such as this, the heater output power is proportional to the well temperature over a limited range of temperatures around the set-point. This range of temperature is called the proportional band. At the bottom of the proportional band, the heater output is 100 %. At the top of the proportional band, the heater output is 0. -
Page 20: Controller Configuration
9103 User’s Guide Controller Configuration The Product has a number of configuration and operating options and calibration parameters which are programmable from the front panel. These are accessed from the secondary menu after the proportional band function by pushing SET. push SET again to enter the first of three sets of configuration parameters —... -
Page 21: Sample Period
Dry-Well Controller Operation Sample Period The next parameter in the serial interface parameter menu is the sample period. The sample period is the time period in seconds between temperature measurements transmitted from the serial interface. If the sample rate is set to 5, the Product transmits the current measurement over the serial interface approximately every 5 seconds. -
Page 22: Calibration Parameters
9103 User’s Guide Calibration Parameters The operator of the Product controller has access to a number of the calibration constants: R0, ALPHA, DELTA, and BETA. These values are set at the factory and must not be altered. The correct values are important to the accuracy and proper and safe operation of the Product. -
Page 23: Serial Communications
Dry-Well Digital Communication Interface Serial Communications The Product is installed with an RS-232 serial interface that allows serial digital communications over fairly long distances. With the serial interface the user can access any of the functions, parameters and settings discussed in Controller Operation with the exception of the BAUD rate setting. -
Page 24: Setup
9103 User’s Guide Setup Before operation the serial interface must first be set up by programming the BAUD rate and other configuration parameters. These parameters are programmed within the serial interface menu. The serial interface parameters menu is outlined in Figure 4. To enter the serial parameter programming mode: 1. -
Page 25: Serial Operation
Dry-Well Digital Communication Interface Serial Operation Once the cable has been attached and the interface set up properly the controller immediately begins transmitting temperature readings at the programmed rate. The serial communications uses 8 data bits, one stop bit, and no parity. The set-point and other commands can be sent with the serial interface to set the temperature set-point and view or program the various parameters. - Page 26 9103 User’s Guide Command Command Returned Acceptable Command Description Returned Format Example Example Values Configuration Menu Operating Parameters Menu Read High Limit hl: 999 hl: 140 Set High Limit hl=n hl=90 0-140 Serial Interface Menu Read serial sample setting sa[mple] sa: 9 sa: 1 Set serial sampling setting to n seconds...

Dry-Well Test Probe Calibration Test Probe Calibration For optimum accuracy and stability, allow the Product to warm up for 25 minutes after power-up and then allow adequate stabilization time after reaching the set-point temperature. After completing operation of the calibrator, allow the well to cool by setting the temperature to 25 °C for one-half hour before turning off the power. -
Page 28: Calibration And Adjustment Procedure
9103 User’s Guide Calibration and Adjustment Procedure Sometimes the user may want to calibrate the Product to improve the temperature set-point accuracy. Calibration is done by adjusting the controller probe calibration constants R0, ALPHA, DELTA, and BETA so that the temperature of the calibrator as measured with a standard thermometer agrees more closely with the set-point. -
