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 45V, 100V, 250V and 500V the device fulfils
most test specifications 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
set point processing. When the measured value
falls below the set lower limit the setpoint
value switches and therefore activates a
potential-free relay output. The Megohmmeter
is the right instrument for use in laboratory
as well as industrial applications.
The complete control via RS232 PC-interface
enables the setup of fully automatic test
stations. So it is possible to integrate the
instrument into production process control
routines.

| Description |
 |
The
digital megohmmeter 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. 5 pA up to 10 mA with a test voltage
of 45V, 100V, 250V and 500V. 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 put
on the backside.
