6.4 Resistance Simulation []
The resistance simulator is capable of simulating resistors using
2-wire connection for the following range: 5  2000 .
2-Wire Resistance Calibrator
Device to be Calibrated
–
Input
+ Measuring Current: 50 A ... 5 mA
➭ Select the  calibration function with the rotary switch.
➭ Switch the calibrator on by pressing the ON / OFF | LIGHT key.
➭ Connect the device to be calibrated with the measurement
cable as shown.
➭ Set the resistance simulation value:
ON indicates: The output is active!
Select the digit to be changed with the   keys, and change
the respectively selected digit with the  keys.
➭ The output can be activated with the OUT | ENTER key, or
deactivated [ Stdby ] once again.
Switching Between the Fixed Value, Interval and Ramp Functions
➭ Press the ZERO / SEL | ESC key in order to switch to the
[ select range ] menu.
➭ Switch to the interval or ramp function menu with the  
keys. Start the respective function with OUT | ENTER.

Note
The following error messages are possible: "HiCurr" (high
current – current value to high) where I > 4.5 mA and
"LoCurr" (low current – current too low or reversed polarity)
where I < 40 A (corresponds to unconnected sockets).
No external voltage may be applied to the calibrator jacks
in this operating mode.
The calibrator is protected against brief application of a
large external voltages with a replaceable fuse in the event
of operator error (see section 10.3).
Response time of the calibrator output to the specified resistance
value after measuring current is applied is max. 30 ms. Devices
under test with non-continuous measuring current (e.g. scanned
measuring inputs) result in erroneous measured values, if
measurement is started before response time has elapsed. The
calibrator cannot be used for devices of this type.
