Description
Product withdrawn from the offer
The Sonel MIC-2505 insulation resistance meter is a budget version of the Sonel MIC-2510 meter. Perfect for the start.
The modern, ergonomic casing and very simple and intuitive operation are particularly important when taking a large number of measurements. All settings of modes and measurement voltages are made using the rotary switch.
Specifications
AC / DC voltage measurement
⇒ Abbreviation "m.v" used in the specification of measurement uncertainty means a standard measured value
| Display range | Resolution | Accuracy |
|---|---|---|
| 0 V...600 V | 1 V | ±(3% m.v. + 2 digits) |
- Frequency range: 45 Hz...65 Hz
Measurement of insulation resistance
Measuring range according to IEC 61557-2: \( R_{ISOmin} =\frac{U_{ISOnom}}{I_{ISOnom}}\)…2,000 TΩ (IISOnom = 1 mA)
Double-lead measurement
| Display range | Resolution | Accuracy |
|---|---|---|
| 0.0 kΩ...999.9 kΩ | 0.1 k Ω | ±(3% m.v. + 20 digits) |
| 1.000 MΩ...9.999 MΩ | 0.001 MΩ | ±(3% m.v. + 20 digits) |
| 10.00 MΩ...99.99 MΩ | 0.01 MΩ | ±(3% m.v. + 20 digits) |
| 100.0 MΩ... 999.9 MΩ | 0.1 MΩ | ±(3% m.v. + 20 digits) |
| 1.000 GΩ...9.999 GΩ | 0.001 GΩ | ±(3% m.v. + 20 digits) |
| 10.00 GΩ...99.99 GΩ | 0.01 GΩ | ±(3% m.v. + 20 digits) |
| 100.0 GΩ...999.9 GΩ | 0.1 GΩ | ±(3% m.v. + 20 digits) |
| 1.000 TΩ ...2.000 TΩ | 0.001TΩ | ±(3% m.v. + 20 digits) |
Approximate maximum values of the measured resistance, depending on the test voltage, are presented in the table below. For other voltages the range limits may be read from the chart below.
| Voltage | Test range |
|---|---|
| 500 V | 500 GΩ |
| 1000 V | 1,00 TΩ |
| 2500 V | 2,00 TΩ |
⇒ Note: For insulation resistance below RISOmin there is no accuracy specified because the meter works with the adjustable current limit in accordance with the following formula:
\( R_{ISOmin} =\frac{U_{ISOnom}}{I_{ISOnom}}\)
where:
RISOmin - minimum insulation resistance measured without limiting the converter current
UISOnom - nominal test voltage
IISOnom - nominal inverter current (1mA)
