Temperature Measurement; Rel Function - VOLTCRAFT 12 29 18 Notice D'emploi

g) Temperature measurement
- Insert the temperature measurement adapter supplied into the meter's two mea-
suring sockets. Ensure you insert them in the correct polarity. The adapter
marked with a „+" must be connected to the red V connector (11).
- Insert the lead temperature sensor into the measuring adapter. Ensure you insert
them in the correct polarity. The temperature sensor contact adapter marked with
a „+" must be inserted in connector marked with a „+" or the measurement
adapter.
Any commercially available K-type temperature sensor with a mini-
socket can be used.
The lead temperature sensor supplied is suitable for temperature
measurements for -40 to + 250 °C.
- Turn the meter on at the rotary switch and select the measuring range TEMP
(VC-521).
- With the Mode key (7) on the VC-521, select the units „°C" (degrees Celsius) or
„°F" (degrees Fahrenheit).
- On the VC-520 you can directly select the units „°C" (degrees Celsius) or „°F"
(degrees Fahrenheit) with the rotary switch.
- The temperature will be displayed on the meter - it can take up to 30 seconds
until the value stabilizes.
- After measuring, remove the measuring adapter from the meter and turn the
meter off. Turn the rotary switch to „OFF".

REL Function

The REL function allows a reference value measurement to avoid possible line loss-
es which may caused e.g. during resistance measurements or to adjust for residual
magnetism in the current sensor. For this purpose, the current indicated value is set
to zero. A new reference value is set.
Press the „REL" button (8) to activate this measuring function. „REL" appears on the
display.
