The TAP must not be used for anything other than the below-stated purposes.
The TAP should not be exposed to moisture or used in damp or wet environments.
Remove refrigerants from the TAP and the hoses after use.
Purpose and use
The TAP has been developed for measuring pressure and temperature in both mobile
and stationary refrigeration equipment.
TAP is only designed for temporary measurement, don`t use it as a stationary long term
measurement unit.

Risk of short circuit. If the electronic components come into
contact with water, short circuits are possible. Dunk the TAP-
CLAMP below max. water level as shown.
1. Prepare ice water:
Take your time, use lots of ice and stir wa-
ter often. It can take up to 15 minutes for
the ice water temperature to settle exact-
ly at 0.0 °C / 32.0 °F Use separate accura-
te thermometer to verify water temp.
For best results use an insulated cup, do
not let the sensor tips touch any ice cu-
bes, only the ice water in the top 2-3 cm
of the ice bath after +/- 15 min. Do not
touch or hold the sensor wires.

Calibration
The accuracy of all measuring devices will degrade over time. Calibration improves the
accuracy of the TAP. On this device temperature and pressure can be re-calibrated.
Temperature calibration can be done using two procedures: calibration using ice water
as reference or by using room temperature as reference.
Calibration of temperature clamp
Risk of short circuit. If the electronic components come into contact with
water, short circuits are possible. Don`t dunk the temperature clamp below
max. water level. (See figure below)

The TAP must not be used for anything other than the below-stated purposes.
The TAP should not be exposed to moisture or used in damp or wet environments.
Remove refrigerants from the TAP and the hoses after use.
Purpose and use
The TAP has been developed for measuring pressure and temperature in both mobile
and stationary refrigeration equipment.
TAP is only designed for temporary measurement, don`t use it as a stationary long term
measurement unit.
