Insulation Resistance Meter (up to 1 kV)
The MIC-1000 is a small, portable meter for measuring the insulation resistance of electrical and telecommunication installations, cables, transformers, motors, machines and other devices. The measuring voltage can be programmed with 10V step. The instruments can measure both: the insulation resistance in a very wide range 50k..110G (110 000M) and the leakage current of the insulation. All the test results can be stored in the internal memory and send to a computer via serial interface. The meters are supplied with Ni-Cd batteries and charger as standard.
- type of insulation: double, according to EN 61010-1 and IEC 61557
- measurement category: CAT III 300V acc. to EN 61010-1
- protection class acc. to EN 60529: IP40
- converter’s current: max. 1,4mA
Other technical data:
- power supply: battery set Ni-Cd
- time to auto-off:
- mode RISO/IL: depends on T2 or T3 (T2/T3 + 300 seconds) settings
- other modes: 300 seconds
Rated operational conditions:
- operating temperature: -10...+40°C
- storage temperature: -20...+60°C
- measurement rate: approx. 1 measure/second
• for measurements of limited converter current, the accuracy is not specified.
AC voltage measurement
50Hz (sinusoidal shape with harmonic contents < 2%)

Leakage current reading
| Range | Resolution | Accuracy |
| 0...Ipmax | depending from range | -ΔI-, +ΔI+ |
Ipmax - maximum converter’s current equal to 1,2 ± 0,2 mA,
ΔI-, +ΔI+ - current reading accuracy calculated from the resistance reading using the formulas:
UISO - test voltage
R - displayed value of the insulation resistance
ΔR - resistance measurement accuracy defined for the measurement
