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
CL3001 as shown in figure 13.

Ω
Output Connection
f)
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.
h) When RTD/
Ω
mode is first selected, the CL3001 is placed in the
standby (Stby) mode which puts the positive (+) output jack into
a high impedance state (>100k ohm) for safety. To place the
output into the active state, press the
key which toggles
between the standby and operate modes.
