Insulation and Resistance Measuring Instrument
with Voltage Measuring Range
GMC-I Messtechnik GmbH
Features
Nominal Voltages: 100 V, 250 V and 500 V
The instrument is suitable for the measurement of insulation
resistance at voltage-free devices and equipment with nominal
voltages of up to 500 V.
Low-Resistance Measurement: 0 ... 4 Ω
Low-resistance measurement is performed in accordance with
VDE 0413, part 4. It is used for testing resistance at ground
cables, protective conductors and equipotential bonding
conductors, including related connections and terminals.
Voltage Measurement to 500 V
The instrument is also equipped with a 500 V measuring range for
direct and alternating voltages. This provides users with the
advantage of checking devices under test for the absence of
voltage, and discharging capacitive devices under test.
Minimal Battery Depletion
Measurement is only performed in the resistance measuring
ranges when the MΩ or Ω key is pressed. Battery service life is
maximized in this way.
Voltage measurement can be performed without using the
battery.
