Fast and accurate measurements of the smallest resistance values are possible with the milliohmmeter RESISTOMAT® model 2316. Due to the rugged aluminium injection moulding desktop housing with membrane keypad it is suitable for use in laboratory and industrial environment likewise. Wires and coils can be measured with temperature compensation. The temperature of the sample is measured with a Pt100 or pyrometer and the resistance is then corrected to the equivalent at e.g. 20 °C (adjustable) in the instrument.
The application range is very wide such as the measurement of:
For a cooling curve recording with freely selectable time interval a data logger for up to 1000 values is available. The complete control via RS232 interface enables the setup of fully automatic test stations. The instrument features a PLC interface for integration into production process control classification and makes selection of the samples an easy task.
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 Pt100 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 specifi c 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 available interfaces.
The high-contrast LCD display with backlight assures very good reading of the measurement value in dark as well as bright spaces.
