MULTIGAS PUMP CARTRIDGE
USING PUMP
Where do I see my pump details?
When a pump cartridge is attached to G7, you can see the pump status screen by
pressing the up or down arrow from G7’s main screen. Here you can see if pump is on or
o, your hose length, ow rate and sample time (if enabled).
How do I bump test or calibrate my pumped cartridge?
Manually bump testing and calibrating pump cartridges is done using the same
calibration cap and method as G7’s multi-gas cartridge. Please refer to page 14-16 of this
manual for step-by-step instructions. G7 cannot be bump tested or calibrated through
the pump itself.
Bump testing and calibrating with a G7 Dock requires an updated G7 Dock unit. You can
tell if your Dock is an updated unit by checking that it’s unit ID is Dock-P.
How do I perform a block test?
You will be asked to perform a block test upon entering any pumped mode, such as leak
check, pre-entry or pump run. Follow the steps on G7’s screen to complete the block
test. If you do not pass the block test, you will not be able to enter the mode.
IMPORTANT: When performing an automatic block test, G7 is in a safe mode where gas
alerts will not be triggered. This prevents triggering false alerts from residual gas in the
tubing.
When you are in a pumped mode, you can perform a manual block test at any time by
plugging G7’s inlet. This will cause G7 to go into yellow warning alarm, and your screen
will let you know that your pump is blocked. Unplug your inlet, and if the warning alarm
silences, you know that your equipment is safe to use.
