dipper-Temp temperature meter Instructions
General Care of Heron dipper-Temp
Heron Instruments Water Level Meters are quality, robust units that will give many years of reliable service if these recommendations are
followed:
Avoid sharp edged casing, use the tape guide on the unit.
Take care to avoid the tape becoming entangled with other equipment in boreholes or wells, use stilling pipes when possible.
DO NOT use the dipper-Temp as a guide to backfilling, bentonite sealing or sand packing in wells. This type of material falls through the
water column at a much slower rate than the dipper-Temp probe and can result in a trapped probe and tape.
Neatly rewind and clean the tape after each use.
Refer to: Cleaning the Heron temperature meter
Warranty is conditional upon adherence to these guidelines
Equipment Check
Before taking the unit into the field, carry out these simple tests. Push the test button in air, unit will display air temperature (see Figure 1),
and make sure the two panel retaining thumb screws (nuts) are tight.
The unit is off until the probe is in water or the test button is pushed. Pushing the test button in air gives the air temperature.
NOTE: There is no on/off switch on the instrument, the water is the switch. The dipper-Temp consumes no power when the probe is not in
water.
When LOW BATT is displayed, the 9 volt battery must be changed as soon as possible. NOTE: Accurate battery orientation diagram inside of
battery box. (See Figure 1)
Use in the Field
Reel the tape down the well carefully avoiding the edge of the casing. Hang the dipper-Temp on the casing when possible and run the
tape over the guide on the frame leg to avoid cuts and nicks to the tape. Swivel the probe holder on the frame to allow the tape free
movement down the well (See Figure 3). NOTE: The inverted triangle on the probe holder serves as a datum point indicating “top of
casing”.
When the unit sounds, carefully measure the depth to water indicated on the tape from your reference point. Raise and lower the probe in
and out of the water to get a consistent result for water level. Push the left black button to switch the audio signal off, if only doing
temperature profiling.
The right black button is the test button. When pushed, It will signal with an audio and visual indication and will display the temperature in
Celsius.
The temperature reading may take 30 seconds to stabilize.
DO NOT use the dipper-Temp to measure the progress of back filling wells. The tape and probe may become trapped in the backfill
material.
DO NOT allow the tape to “freewheel” down the well. It may become caught in other equipment in the well.
When rewinding the tape remove as much water and debris as possible from the tape and the probe.
Cleaning the Heron dipper-Temp
Always clean the meters after use in the field to maintain optimal performance and extend the life of the unit.
The dipper-Temp may be cleaned with any mild household dishwashing detergent and rinsed with water.
DO NOT use abrasives, partially halogenated hydrocarbons or ketones to clean the reel. If the electronic panel is removed first, the reel and
tape can be washed with a power washer.
Remove the panel retaining thumb screws (nuts) to release the panel. Take care not to lose the thumb screws as the unit will not work
without them.
For longer units with aluminum reel discs, the panel is connected to the tapes with male and female push connectors.
Troubleshooting the Heron dipper-Temp
Q. No sound or light when the unit is tested.
A. Refer to Equipment Check and follow procedures. Change the battery.
Q. Equipment checked, panel okay but probe not working.
A. Make sure both panel retaining thumb screws (nuts) are tight.
Q. Still not sounding in water.
A. Adjust the sensitivity setting. If the unit still does not work
check all the connections inside the hub (inside the hub polarity is not an
issue as the current is AC).
Contact Heron Instruments or your supplier if you cannot isolate the problem.

Test Button
Buzzer
Thumb Screws (Keep Tight)
To test entire system: Make sure sensitivity dial is turned fully clockwise. For the Water Tape, hold the center pin on the probe against the stud on
the back of the axle; touch the probe body against the screw on the frame at the same time. For the Skinny Dipper, touch the last probe
weight and the probe body with metal material (wire) at the same time.The buzzer will sound if the system is okay.
Unique hanger and tape protector supports the meter on the casing and protects the tape from sharp edges on the well casing.
IMPORTANT: ENSURE THAT THE PANEL RETAINING THUMB SCREWS (NUTS) ARE TIGHT BEFORE USE.
