d) Resistance
Measurement ways include two-wire, three-wire and four-wire measurement.
To perform a resistance measurement, press
to enter
mode,
then press
to select resistance functionality (the displayed unit is Ω). 2W, 3W
and 4W measurement ways are displayed on the top left corner of the screen.
Refer to the figure on the right for connecting the test leads.
Resistance measurement
e) Thermal resistance
The calibrator can measure thermal resistances with different graduations, such as Pt100, Pt200, Pt500, Pt1000,
Cu10, Cu50, Cu100, PT100-392, PT100-JIS, Ni120, etc. It can also measure 2W, 3W and 4W RTD. The 3W is the
most common measurement way, the 4W is with the highest precision, while 2W is with the lowest precision.
Press
to enter
mode, the connection method is the same as resistance measurement.
Thermal resistance measurement
f) Thermocouple
The calibrator can measure 10 models of thermocouples, including R, S, K, E, J, T, N, B, L, U.
1. Press
. The thermocouple reading will be displayed.
2. Press
one more time to select appropriate model of thermocouple.
3. Press
to set up the manual cold junction compensation.
4. Short press
to switch to automatic compensation.
Refer to the figure below for connecting the test leads.
