Application

Based on its specifications, this device can be used in various applications. It is especially suitable for resistance measurement on insulating materials such as e.g. cable insulations, foils, textiles, surfaces, insulating liquids, etc. With a test voltage of 45 V, 100 V, 250 V and 500 V the device fulfi ls most test specifi cations such as e.g. DIN 51953, 53482 and 54345.

The guard switching allows single resistance measurements in a triangle wiring. This could be e.g. a two line cable with common shield or the measurement of insulating materials on a guardring measurement cell.

The selection of the measurement range is done manually or automatically. Fast subsequent measurements can be realized by the internal limit value indicator. When the measured value exceeds the limit the limit value indicator switches and activates a potential-free relay output. The megohmmeter RESISTOMAT® model 24508 is the right instrument for its use in laboratory as well as in industrial applications.

Description

The megohmmeter RESISTOMAT® model 24508 is a microprocessorcontrolled measurement device for insulation resistances. The device has an easy-to-use structure in a sturdy metal housing. Easy access to the interior components allows an optimal service.

The measurement range stretches from 50 kΩ up to 10 TΩ resp. 10 pA up to 10 mA with a test voltage of 45 V, 100 V, 250 V and 500 V. The configuration of the device is done via the two line LCD display with the help of the simple menu structure.

It goes without saying that all configurations can also be effected via the RS232 interface. The connections for the potential-free limit output as well as the external measurement start / stop are located on the backside.
