4.4 Resistance Temperature Detector (RTD) and Ohms Source
The 3001 can source all common RTD types and 5 custom RTD curves in °F or °C, plus
basic resistance from 5 to 4000 ohms.
The following common RTD types are supported:
Pt 385
100
Ω, 200Ω, 500Ω, 1000Ω
Pt 3926
100
Ω
Pt 3916 (JIS)
100
Ω
Ni120
120
Ω
Cu 427 (Minco)
10
Ω
YSI 400
a) Disconnect any test leads from external devices.
b) Press the
key to select thermocouple and RTD/
Ω mode, if not already
selected. If thermocouple mode is displayed, press the key again to cycle to RTD/
Ω
mode.
c) If input mode is displayed, select output mode by pressing the
and
keys.
d) Press the
key to select the desired RTD curve or ohms range. The set up
and use of custom RTD coefficients is described in section 4.5.
e) Connect the unit under test to the RTD/
Ω output terminals of the 3001 as shown in
figure 13.

Press the
and
keys to toggle the RTD display between °F and °C.
g) Use the numeric keypad to enter the desired output value and press the
key.
Alternatively, use the
or
cursor key to select a digit to modify, followed by the
or
cursor key to ramp the digit up or down. This method offers a simple
solution when small changes to an output value are required, or if specific decades
need to be incremented or decremented.
