at different temperatures, wait at least 3 minutes for the miniplug
and terminals to stabilize to the same temperature.

Press the
and
keys to toggle the thermocouple
display between °F and °C.
g) Press the
and
keys to toggle the cold junction
compensation between the internal temperature sensor and an
external reference.
h) For best accuracy, it is advisable to zero the T/C millivolt circuit
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 ±1 mV.
To zero the T/C millivolt circuit:
• Select the thermocouple measure function as described
above, and press the
key until the millivolt range is
selected.
• Insert the supplied thermocouple shorting jumper into the
thermocouple terminals.
• Allow at least 3 minutes for the jumper and terminals to
stabilize to the same temperature.
• Press the
and
keys to zero the T/C millivolt circuit.
4.8 Thermocouple (TC) Source
The CL3001 can source all common thermocouple types in °F or °C,
plus basic millivolts from -10.0 to 75.0 mV.
The following common thermocouple types are supported:
B, C, E, J, K, L, N, R, S, T, U, XK, BP
