Multiple gas cylinders may be required to fully bump test the monitor.
Each gas cylinder used is referenced using a CalGas number.
For example:
• CalGas1 - Methane PPM
• CalGas2 - Methane LEL
• CalGas2 - Methane Vol
• CalGas4 - CO/H

1. The current CalGas selection number is highlighted. A different CalGas number can be
selected by pressing the UP
or DOWN
buttons.
In the example in
Figure 75: Example CalGas Cylinder
, a cylinder of 50% LEL is assigned to
CalGas2.

2. To enter/edit the gas cylinder concentration, press and hold the NEXT button to highlight
the gas value to be altered (as shown in
Figure 76: Enter/Edit CalGas Value
). Press the UP
or DOWN
buttons as necessary to enter the correct gas value.

3. Once the monitor has been programmed with the actual gas cylinder content, press and hold
the OK button to start the test. The screen shown in
Figure 77: Applied Gas Peak Values
be displayed.
Note: Bump Test mode will only display gas ranges configured in the monitor.
Note: Pressing and holding either of the buttons will rapidly increase/decrease the
gas value.
