Megaohmmeters ES0202/1-G and ES0202/2-G (ЭС0202, ЭСО202, ЭСО 202/2Г, ЭС 0202, ESO202, ES 0202/2G), with built-in hand generator, 100–2500 V
Country: Ukraine · Model: ES0202
Megaohmmeters ES0202/1-G and ES0202/2-G, often searched as ЭСО202 or ESO202, measure insulation resistance of de-energized circuits. The built-in hand-driven generator supplies the power, so no mains or batteries are needed. The /1-G reads up to 1000 MΩ at 100, 250 and 500 V, the /2-G up to 10 000 MΩ at up to 2500 V.

Description
The instrument has a pointer scale. It applies a test voltage to the circuit and reads insulation resistance in megaohms. Discharge the circuit before testing. The generator handle turns at 120–144 rpm, so the megaohmmeter works at a substation, in a cable well or in a workshop without a power socket. Basic relative error is ±15 %. Operation is intermittent, one minute of measurement then two minutes of pause, so long cable tests need that pause built into the plan. Operating temperature from −30 to +50 °C, GOST 22261 group 3 with extended range. Used for cables, motors, transformers and acceptance tests. Its designation is written in several ways, such as ЭС0202, ЭСО202, ЭСО 202/2Г, ЭС 0202/2Г, ЭС0202-2Г, ЕС0202/2-Г or ES0202/2G, and all of them mean one instrument.
How to choose
Choose by voltage and range. Up to 1000 MΩ at 100, 250 and 500 V, take ES0202/1-G. Up to 10 000 MΩ at 2500 V, take ES0202/2-G. We will match version and kit to your task, so write to a USK ENERGY manager.

FAQ
Are ЭСО202 and ЭС0202 the same instrument?
Yes. The correct spelling is ЭС0202, with the digits 0202 after the letters. Variants such as ЭСО202, ESO202, ЭСО 202/2Г or ES 0202/2G are common, but they name the same megaohmmeter.
What voltage do ES0202/1-G and ES0202/2-G provide?
ES0202/1-G has three settings, 100, 250 and 500 V, with a scale up to 1000 MΩ. ES0202/2-G measures up to 10 000 MΩ at up to 2500 V.
Does the ES0202 need batteries or mains power?
No. A built-in electromechanical generator supplies power, and the handle turns at 120–144 rpm.
What is the error and operating temperature of ESO202?
Basic relative error is ±15 %, operating temperature from −30 to +50 °C.
How long can it measure without a break?
Operation is intermittent, one minute of measurement then two minutes of pause. Plan these pauses into long cable tests.
