NOTE:
CAUTION
MAINTAIN CORRECT TEMPERATURE
For T/C: Use compensation lead wires as the selected thermocouple. For RTD, mA: Use the copper lead
wires. In thermocouple pay attention to the ambient temperature. If you are using a mV generator instead
of direct thermocouple generator, the lead wires are in copper and you have to subtract from the mV value
the mV corresponding to the ambient temperature of the rear terminals. (This eliminates the effect of the
cold junction compensation)
Failure to comply with these instructions may result in product damage
NOTE:
PARAMETER
PV CALIB
Signal generators should have an accuracy of at least 0.05 %.
The type of wires depends on the sensor used.
Wait for 5 minutes after that particular sensor is connected (For compensation
wires only).
Each time you change the sensor, the recorder is factory calibrated again.
