The unit will make a brief audible tone when the battery is first installed, until the auto
off feature powers the unit down into the sleep mode after 15 minutes. When the
unit is on, but not in any liquid, the red LED with flicker briefly every few seconds, so
that the operator knows the unit is turned on.
IV. Basic Reel Features
The dipmeters come equipped with a probe holder and well casing bracket/hook.
When taking a reading it is possible to hang the reel from the well casing and use the
frame leg to guide the tape into the well. The frame leg should protect the tape from
the sharp edges of the well casing. In the event the tape will be exposed to the well
casing’s sharp edges, do not use the reel in the above position but order a separate
tape guide suitable for your specific requirements.
The unit has a reel brake at the back of the frame. To lock the reel, tighten the brake
in the clockwise direction.
If equipped, make certain to use the grounding strap located at the back of the reel.
Additional Features-Pump Monitoring Mode
During a pump test or draw down test, the unit can be used to alert the operator that
the pump will run dry soon.
While the unit is in any liquid, hold down the start button for at least 4 seconds, and
the audio signal will stop and the unit will go into pump alarm mode.
Once the probe is removed from the liquid or the liquid level drops below the probe,
the audio signal will resume.
