MEGAOHMMETERS ЭС0210, ЭС0210-Г
The performance of megaohmmeter ЭС0210 is splash and waterproof
Megaohmmeters ЭС0210, ЭС0210-Г are designed to measure the insulation resistance of electrical circuits which are not energized and the rms value of an AC or DC voltage values on the measured object. The megaohmmeters provide discharge capacity of the object after measurements.
The range of insulation resistance measurements, the range of the measured voltages and measuring voltage at the terminals of the megaohmmeters at open external circuit are given below:
|Identification mark||Measurement range||The measuring voltage, V|
|of resistance, MOhm||of voltage, V|
|Accuracy class of megaohmmeters, expressed as reduced error according to GOST (ГОСТ) 8.401-80, 2.5.|
- Limits of basic errors:
- ± 2,5% of the length of the scale when measured resistances;
- ± 2,5% of the upper range value of voltage;
- ± 15% of measured resistance (a relative error).
- Limit values for insulation resistance measurement errors expressed as reduced to the length of the scale and as a relative are equivalent. Limits of the basic errors of the measurements are normalized to the working part of the scale, a marked point. For megaohmmeters ЭС0210/3, ЭС0210/3-Г when measuring resistances in the measuring range from 500 MOhm to 100,000 MOhm (scale IIx10), a measurement error is normalized only for voltage 2500 V.
