Milliohmmeter - RESISTOMAT® 2316
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:
transformer motor coil windings
coils of all kind
cables and wires on the drum or as meter samples
switch and relay contacts
heating elements
fuses
connections and transitions at power rails and many more
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.
