The device works according to the proven 4-wire measurement method which eliminates errors caused by test lead and contact resistances. Thermo voltages that might be in the measurement circle would be compensated automatically by this measurement method. The control of the measurement leads is done with an integrated cable fraction detection.
A temperature compensation for any given sample material such as copper, aluminium, tungsten, etc. is self-evident. The temperature measurement is done by an external Pt 100 sensor or by an external infrared measurement device (ref. to accessories).
A special measurement voltage input protection was developed for testing large inductive samples so that voltage peaks do not cause permanent damage while pinching off the sample.
16 device settings such as the measurement range, limit values, temperature coeffi cient, etc. can be saved in order to test samples with different parameters in an automatic measurement system. All device specific settings are shown to the user via display.
Calling up the settings is done via keypad or via PLC interface with a bit pattern (4-bits). It goes without saying that all device settings may also be effected via the RS232 interface.
The high-contrast LCD display with backlight assures very good reading of the measurement value in dark as well as bright spaces.
