This product has now been discontinued, and is replaced by the MIT300 series
- No scale multipliers
- Multiple test voltages for spot and step voltage testing
- Guard terminal to eliminate surface leakage current
The MJ459 and MJ159 replace the BM12 and MJ10, respectively.
Four models are available for general purpose testing which include a low-voltage model.
All are portable, self-contained instruments designed to give rapid and accurate measurements.
Four of the models feature an analog display having four selectable test voltages of 100, 250, 500 and 1000 V dc, measuring insulation resistance up to 2000 MΩ and an ohm range to 5000 ohms. The other model has four test voltages of 50, 100, 250 and 500 V dc measuring insulation resistance up to 1000 MΩ.
