Using the Universal Pump Probe
1. Press the POWER ON/OFF button.
• The audible alarm sounds.
• The pump motor starts fast and then slows down as the pump
speed is automatically adjusted.
• Once the pump is ready for use, the green LED flashes once
per second.
2. Plug the free end of the sampling line or probe.
• The pump motor shuts down.
• The audible alarm sounds.
• The red LED flashes.
3. When the pump inlet, sample line or probe is blocked, the pump
alarm must activate. If the alarm does not activate:
• Check the pump, sample line and probe for leaks
• Once the leak is fixed, recheck the pump alarm by blocking
the flow.
4. Check the pump before each day's use.
Do not use the pump, sample line, or probe unless the pump
alarm activates when the flow is blocked. Lack of an alarm is
an indication that a sample may not be drawn to the sensors,
which could cause inaccurate readings. Failure to follow the
above can result in serious personal injury or death.
Never allow the end of the sampling line to touch or go
under any liquid surface. If liquid is sucked into the device,
readings will be inaccurate and the device could be dam-
aged.
5. Press POWER ON/OFF button to reset alarm and restart pump.
During operation, a pump alarm may occur when the:
• Flow system is blocked
• Pump is inoperative
• Sample lines are attached or removed
• Filters become clogged with excessive dirt or debris.
