If a Module that had previously lost communication regains communication, the module name cell in the
Recording View turns YELLOW (see below) and remains YELLOW through the rest of the run.
24 Valve Open – Clicking a cell within this row puts a check mark in the box () and opens the vent valve
for that specific Module for a maximum of 3 minutes. Clicking the cell again removes the check mark
() and closes the specific vent valve. This should NOT be done during a study because the computer
will not record any pressure loss during this operation. This function allows you to open and close valves
for individual Modules. Remember that you can open and close all valves at once by using the
Open
Valves and Close Valves buttons in the Configuration View.
Holding the vent valve open may reduce battery voltage. Before clicking the
Record button on your GPM screen to start the study, replace batteries that
show 6.6 volts or lower.
25 Pressure Release – Cells in this row display the maximum pressure setting for the respective Module
relative to the Reference Module Zero pressure. If pressure within a module climbs above this value, the
valve will briefly open and vent the gas at the next live interval. The
Current Pressure cell will turn
LIGHT BLUE when this occurs. The computer automatically accounts for pressure lost during this valve
venting. Once the Pressure Release value has been entered on your computer screen, press <Tab> or
<Enter> on your computer keyboard to activate that Module.
The GPM software will not allow a release pressure greater than 10 psi. For
1.8L wide-mouth bottles, it is recommended that you set the
Pressure Release
to a value no greater than 1 psi.
