Resistance Temperature Detector (Rtd) And Ohms Measure - Omega CL3001 User Manual

The standby mode is also activated in the following situations:
• No connection made to the output terminals.
• The voltage compliance for a given output current is exceeded.
The CL3001 has a typical voltage compliance of 10V so that 4-
20mA application loads of up to 500 ohms can be driven. At
maximum current of 100mA, the maximum load is 100 ohms.
4.3 Resistance Temperature Detector (RTD) and Ohms
Measure
The CL3001 can measure all common RTD types, 5 custom RTD
curves, and a custom SPRT in °F or °C, plus basic resistance from 0
to 4000 ohms.
The following common RTD types are supported:
Pt 385
Pt 3926
Pt 3916 (JIS)
Ni120
Cu 427
YSI 400
a) Disconnect any test leads from external devices.
b) Press the
if not already selected. If thermocouple mode is displayed,
press the key again to cycle to RTD/Ω mode.
c) If output mode is displayed, select input mode by pressing the

d) Press the
curve, the SPRT, or the desired ohms range. The set up and use
of custom RTD coefficients is described in section 4.5. The set
up and use of SPRT coefficients is described in section 4.6.
e) Connect the unit under test to the 4 wire RTD/Ω input terminals
of the CL3001 as shown in figure 12.
