CALIBRATION
1.
2.
3.
In room temperature application adjust CAL to give the
same reading as a known temperature reference.
This meter will give a direct reading in °C from a K type (chromel-alumel) thermocouple sensor. The circuit uses a converter/amplifier
which has Cold Junction Compensation. Calibration is by two 20-turn cermet potentiometers which allow sensitive adjustment of the
instrument. The meter can also operate without a thermocouple to read room temperature. The meter is housed in a robust carrier,
which can be bolted in place or panel mounted using the low profile bezel, window and clips provided. The meter can also be backlit for
use in poor visibility.
SAFETY
The user must ensure that the incorporation of the DPM into the user’s equipment conforms to the relevant sections of BS EN 61010 (Safety Requirements
for Electrical Equipment for Measuring, Control and Laboratory Use).

Place thermocouple at 0°C and adjust OFFSET to
read 000.
Place thermocouple at known reference
temperature, eg. 100°C and adjust CAL
Repeat steps 1 and 2 until there are no more
adjustments of CAL and OFFSET required to
give desired readings.
