f)
Press the
and
keys to toggle the RTD display
between °F and °C.
g) For best accuracy, it is advisable to zero the RTD resistance
circuit(s) daily, or if the CL3001 is being used outside of the
ambient temperature range of 18 to 28 °C. The maximum offset
from unit calibration that can be zeroed out is ±0.1 ohm for the
high range and ±0.01 ohm for the low range.
To zero a RTD resistance circuit:
• Select the RTD measure function as described above, and
press the
key until the low or high ohms range is
selected.
• Short the RTD/
Ω
terminals with the test leads normally used for
RTD/
Ω
measurements.
• Allow at least 3 minutes for the test leads and terminals to
stabilize to the same temperature.
• Press the
and
keys to zero the ohms range.
4.4 Resistance Temperature Detector (RTD) and Ohms

The CL3001 can source all common RTD types and 5 custom RTD
curves in °F or °C, plus basic resistance from 5 to 4000 ohms.
