The solenoid will become hot if the valve open check box is left checked. Normal valve openings are very brief and within a range of 10-1000 milliseconds, which does not cause the solenoid cylinder to get hot. If the Open Valves button is clicked or...

The sensors are accurate to within +/-2°C over a range of 5°C - 60°C. To account for any Module-to-Module differences in temperature sensing capability, the GPM software provides a calibration screen that can be used before data recording begins...

Possible Causes: (1) The bag suspender is worn or not properly functioning. Refer to Service Procedure Bag Suspender Check (DES006). (2) The vessel is overfilled with solution. (3) The level sensor is not detecting the solution. To service the blue...

You must run GPM software version 9.7 or greater when operating modules with temperature sensors.

The auto-graphing capability provides the user with a visual indication of the data being recorded during a gas study. However, the graphs themselves are NOT automatically stored after the study is complete. There are three ways to save the graphs...

This is most likely because the default AutoSave location is in a location that your computer may not have "write" access to. In addition, behind the scenes, the program is also attempting to save a log file of every communication between the...

Yes, the Dual Lead Rechargeable Battery ( Part #: RF46) allows you to connect the battery to both the module and the charger while the module is in use. Place the dual lead battery in the module and connect one lead to the module and the other to the...

Fifteen RF modules with 100-500ml size bottles attached will fit in the 20-liter Water Bath (Part #: WB20SH or WB20ISH). Eight RF modules with 1-liter bottles attached will fit in the 20-liter Water Bath (Part #: WB20SH or WB20ISH).

Possible causes include: A loose or disconnected wire from the pressure sensor A faulty circuit board To diagnose, unplug the pressure sensor connector from the circuit board and plug in a pressure sensor connector from a working module into the same...

The pressure sensors are accurate to +/-0.04 psi. Fluctuations in cumulative pressure beyond this correspond to either a leak or a fluctuation in temperature when a module is attached to a sealed bottle. If you check the "valve open" check box, leave...

There may be a problem with the radio frequency (RF) chip attached to the circuit board. This is a dark green/blue colored chip with a black antenna. Refer to RF Service Procedure Chip and Board Replacement (RFS013) for help in identifying the part...

Typically, a fully charged rechargeable battery (Part #: RF16 or RF46) should be able to power a module for approximately ten days under normal conditions (20°- 40°C GPM settings of 60-second Live Interval and one valve opening sequence per hour.) As...

The vessel temperature has exceeded the maximum limit. Possible Causes: The solution level is low in the vessel, but the level sensor is indicating full. The level sensor has two main components that work together. These components are a Level Sensor...
