Page 7: Introduction
• HI% (High Percent) Range: 0–100% by volume is useful in “pin pointing” leaks in underground piping through barhole testing The Gas Pup also features three pressure modes: High (0 to 99 psig); Low (–9.9 to 9.9 psig); and Delta (displays a pressure change in the range of ±9.9 psig from any reference pressure between 0 and 90 psig). -
Page 8: Components
Introduction Gas Pup Components Natural Gas Detection The instrument’s PPM and LO% ranges use a catalytic-bead detection circuit, which is the most widely accepted method of detecting combus- tible gases. The HI% range uses the thermal-conductivity method of detection, which is a reliable method for measuring the concentration of one gas in a second gas (methane in air). -
Page 9: Control Panel Description
Gas Pup Introduction Control Panel Description Two pushbutton controls and a large LCD are conveniently located at the top of the instrument. The backlit LCD provides highly readable indica- tions of natural gas or pressure in any lighting condition ranging from direct sunlight to total darkness. -
Page 10: Gas And Pressure Fittings
Introduction Gas Pup • Bar Graph Window: Provides a real time moving display of the natural gas concentration to give a better ‘feel’ of when the gas level has reached a peak. The bar graph is active only in the PPM and HI% ranges. -

Page 12: Operation
Operating Precautions (Please Read) To ensure that the gas sensor is properly zeroed at startup, the Gas Pup must be turned on in fresh air (free of combustible gases or vapors). Before using the Pup to detect gas, ‘bump test’ the instrument by apply- ing a known concentration of gas to the instrument’s gas inlet port, and... -

Page 14: Turning On The Gas Pup
It is also recommended that the probe and hose assembly be connected to the instrument before turning it on. Refer to Figure 5. The Gas Pup is turned ON by momentarily pressing the key for 1 second. Listen for the pump to start and observe that all segments of the display are momentarily turned on. - Page 15 Gas Pup Operation UEr (Version) LCD Segment Test Software Version Battery Voltage RANGE Mode Display Flashing Display / Auto Start Sequence PPM Gas Display Figure 5.

Page 17: Backlighting
This is the default operating mode when no mode selection is made at startup. With the probe and hose assembly connected to the Gas Pup’s gas inlet fitting, begin checking for gas by placing the probe tip into the area to be tested. -
Page 18: Auto-Ranging
LCD shows a very low ppm reading. This will help prolong sensor life by purging the sensor chamber of combustible gas. Auto-Ranging The Gas Pup incorporates an auto-ranging function that automatically switches the PPM Range display between ranges when a range limit is reached. -
Page 19: Ppm Range
Gas Pup Operation PPM Range After the Gas Pup has been turned on, it will default to its PPM range, showing nothing or some portion of a bar graph display. The range window will show a pointer to the “PPM” flag for range defini- tion. -
Page 20: Hi% (High Percent) Range
Operation Gas Pup HI% (High Percent) Range If the gas concentration goes above the upper limit of the LO% range (greater than 5.0%), automatic changeover to the HI% range occurs. The instrument goes through a 5 second stabilization time period after... - Page 21 Gas Pup Operation Important! Ensure that the instrument’s pressure port is open to the atmosphere during startup, otherwise incorrect pressure readings may result. Before making a pressure measurement, tubing must be connected between the gas source and the instrument’s pressure port. Depending on...

Page 22: High Pressure Mode
Operation Gas Pup High Pressure Mode CAUTION: Maximum over pressure without damage is 150 psig. The high-pressure mode measures pressure in the range of 0 to 99 psig. Enter this mode by first selecting the pressure mode during startup as previously described. The instru- ment will default to its high-pressure mode as signified by the letter “P”... - Page 23 4. Press the key until the letter “d” appears in the RANGE window, indicating that the Gas Pup is now operating in its delta pressure mode. The value “0.0” should now appear in the READING window, indicating that the pressure being measured equals the high-pressure reading just taken.

Page 24: Using The Probe's Filter Chamber
Gas Pup Using the Probe’s Filter Chamber The standard 10" probe supplied with the Gas Pup has a built-in filter chamber that can hold either a foam filter element, or a charcoal filter pack. Install and use these filters as follows: Foam Filter Element –... - Page 25 Gas Pup Operation The petroleum absorbing property of the activated charcoal filter is used to detect petroleum based gases and vapors in the following way: 1. With a standard foam filter installed in the probe’s filter chamber, take a gas sample and note the display indication.

Operation Gas Pup Water/Filter Trap The optional water/filter trap accessory is recommended to be used in conjunction with the 30" barholing probe; thus preventing water from being drawn into the instrument when the probe is inserted into a hole filled with water. The water trap can also be used with the standard 10"... -
Page 27: Error Messages
Error Messages The following is a list of error messages that may appear when operating the Gas Pup. Note that numerical messages appear just prior to the instrument turning itself off. Contact your nearest Bacharach Service Center for assistance if the suggested remedies do not restore the instru- ment to normal operation. -
Page 28: Calibration
Connect the components of the calibration kit, calibration gas cylinder, and Gas Pup together as shown in Figure 18. DO NOT connect the Gas Inlet Fitting to the Pup until instructed to do so in the calibration procedure. -
Page 29: Gas Calibration Procedure
Gas Pup Calibration Gas Calibration Procedure The Gas Pup has an auto-calibration feature that ensures proper calibra- tion of the instrument. After setting up the calibration equipment as previously described, proceed with the calibration procedure as follows: 1. Before turning ON the instrument, be sure that the calibration equipment is not connected to the instrument, and that the instru- ment is in an area of fresh air. - Page 30 Calibration Gas Pup Note: If zero air is being applied at this time, remove it before proceeding to Step 5. 5. While a steady “AC” is being displayed, apply calibration gas by simply connecting the tubing from the calibration equipment to the Pup’s gas-inlet fitting.
