• Notes

• This instrument embodies the facilities of a conventional valve-voltmeter.

  An instrument with a high input resistance. The frequency range of the AC ranges is up to 100 kHz. This limit can be raised over 100 MHz using an external plug-in probe.
  On all ranges, the meter is protected against overload, also when applying reversed polarity.
  Ranges:

  • Three resistance ranges are provided enabling readings up to 100 MΩ.
  • DC Voltage: From 0 to 100 mV to 0 to 300 V.
  • AC Voltage: From 0 to 1V to 0 to 300 V.
  • DC Current: From 0 to 1 µA to 0 to 100 mA.

  The instrument is housed in a modern-styled fibre glass cabinet.
