The device operates on the basis of proven 4-wire technology which corrects any incoming line or contact resistances. The measurement lines are checked by an integrated cable
rupture monitor.
Needless to say, the functions include temperature compensation for various test substances such as copper, brass, tungsten etc. Temperatures are measured by a Pt 100 sensor or infrared sensor (pyrometer) with analog outputs or any temperature transmitter e.g. thermocouple.
For measuring test objects with low inductances, a special measurement input protection was developed to prevent voltage peaks from damaging the device when test objects are disconnected.
If objects need to be tested for several different parameters by an automatic measurement system, you can store up to 32 device settings such as measurement ranges, limiting values, temperature coeffi cients etc. These settings are called up via a bit pattern (5 bits).
Naturally, all device settings can also be made via the RS232 (standard) or IEEE488/USB (optional) interface.
The integrated data logger can be used during serial measurements to store up to 20 000 measurement values which can be divided into 32 individual blocks. A digital fi lter is available for preselecting the measurement values to be stored.
The evaluation menu of the stochastic data logger displays the maximum, minimum and average values as well as the standard deviation.
