8. Technical Data
Only values with tolerances or limits can be taken as guaranteed. Values without tolerances serve purely as
orientation and are not binding.
Te RESISTOMAT
®
model 2329 is easy to maintain and has a robust metal housing. The individual modules
can be accessed and serviced with the greatest of ease.
All the control elements are clearly arranged clearly on the front panel. The connection socket for the test object,
as well as the inputs and outputs for the interface, comparator, Pt100 sensor for temperature compensation
and the control unit are located on the rear of the device.

Measurement error (with temperature compensation inactive):
up to 0.03 % ± 2 digits
This error is valid for a load voltage up to 0.5 V.
At higher load voltages the error increase 0.02 %/V.
Starting time:
< 10 min. to attain the error limits
Max. voltage across the open terminals:
≤
16 V
Measurement connection:
4-wire technique for current-voltage measurement (Kelvin), ungrounded circuit,
potential binding on the test object or the RESISTOMAT®, as required.
Max. load voltage:
≥
5 V
Measurement time:
Up to 50 measurements and evaluations per second,depending on the resolution
and the measurement mode in the case of purely ohmic test objects.
Measurement types:
Continuous and single measurement
Range selection:
Manual, automatic or via interface
Dry-circuit measurement:
According to DIN IEC 512 Part 2
20 mV load voltage limit up to 4
Ω
Temperature compensation:
10 different, individually adjustable temperature coefficients;
individually adjustable reference temperature display (e.g. 20 °C).
Temperature recording:
Via an external Pt100 sensor or transmitter (e.g. pyrometer)
with a voltage (0...10 V) or current output (0...20 mA) or (4.... 20 mA)
Comparator:
2 or 4 limiting values
Relay outputs:
One switching contact each for evaluation results << , < , = , > , >>
