Megohmmeters М4100/1–М4100/5 (М4100, М-4100, M4100), with hand generator, 100–2500 V
Country: Ukraine · Model: M4100
M4100 series megohmmeters, often searched as М-4100 or M4100, measure insulation resistance of de-energized circuits. A hand-driven generator supplies the power, so no mains or batteries are needed. Five models, М4100/1 to М4100/5, differ in test voltage from 100 to 2500 V.

Description
These classic instruments run on a hand-driven generator at a nominal 120 rpm. Operation is intermittent: one minute of measurement, then two minutes of pause, which long cable tests must allow for. The М4100/5 is rated for 2500 V, measures 0–2500 MΩ and has an accuracy class of 1.5. The circuit is de-energized and discharged before measurement. Test voltage matches the equipment voltage class. It checks insulation of installations up to 2500 V, motors and cables in industry and power networks. The designation appears in several forms, for example М4100, M4100, М-4100 or М 4100. It is one series.
How to choose
The choice depends on the test voltage. For low-voltage wiring, the lower models suffice, starting with М4100/1 at 100 V. For higher classes, М4100/5 at 2500 V is needed. When ordering, ask a USK ENERGY manager to confirm the model, measuring limits, kit, verification and documents.

FAQ
Are М4100 and M4100 the same instrument?
Yes. The query is often typed as M4100 or with a hyphen, as М-4100, but these name one series.
How do the М4100/1 and М4100/5 models differ?
By test voltage: 100 V for the М4100/1 and 2500 V for the М4100/5.
Does the М4100 need batteries or mains power?
No. A hand-driven generator supplies the power, with the handle turned at 120 rpm.
How long can it measure without a break?
Operation is intermittent: one minute of measurement, then two minutes of pause.
What is the accuracy class of the М4100/5?
Accuracy class 1.5.
