- From high-volume production of 1600 units per minute to high-precision evaluation of semiconductors
Super Megohmmeter (Output Voltage 2000 V)
With a single instrument, you can measure protective semiconductor elements such as varistors, vehicle capacitors, and other high-voltage components.
Lowest threshold value setting of 0.1 pF
The super megohm meter allows you to perform reliable contact checks on low-capacity capacitors as well as on other measurement objects with small capacitance.
2-band selection
To prevent the check signals on a production line with multiple various measuring instruments from getting crossed, select the measurement frequency for contact checks.
Compatible with external power sources
The contact check function is also available when you use the instrument as an ammeter with an external power source. The instrument is also suitable for measurements over 2000 V.
Cable length correction function
To replace a cable, simply register the measur ing cable length. Time-consuming adjustments are no longer necessary and the instrument can be used for changing the line in a flexible manner.
