Warm-Up Time
For accurate thermocouple measurements, DT9871U and DT9871 TEMPpoint instruments
and thermocouple channels on the DT9874 MEASURpoint instruments require a warm-up
time of 45 minutes for the analog circuitry to stabilize.
For accurate high voltage measurements, the DT9873 VOLTpoint instruments and high
voltage channels on the DT9874 MEASURpoint instruments require a warm-up time of 1 hour
for the analog circuitry to stabilize.
For accurate RTD measurements, the DT9872 TEMPpoint instruments and RTD channels on
the DT9874 MEASURpoint instruments require a warm-up time of 1 minute for the analog
circuitry to stabilize.
