※For different-capacity three-phase four-wires, single-phase three-wires after branching can be measured, ※Three-phase three-wires cannot be measured, and non-grounded circuits cannot be measured.

Number of channels

Voltage 1ch, current 1ch (maximum)

Measurement items

Leakage current effective value (Irms)
Leakage current basic wave value (Io),
Effective leakage current value (Ior),
Ground insulation resistance value (R), etc.

Measuring range

Voltage: AC500V (effective measurement range: 90 V to 490 V)
Current: 20.000mA/200.00mA/2.0000A/5.0000A (effective measurement range is 1% to 110% of the range)

Accuracy

Leakage current effective value: ±0.5%rdg. ±0.2% f.s. + Clamp sensor accuracy
Effective leakage current value: ±0.5%rdg. ±0.2% f.s. + Clamp sensor accuracy + Error due to phase θ accuracy ※Error due to phase θ accuracy (excerpt)
When using 9800: Io≦200 mA: within ±0.5° = Io value × 1.0%rdg.
When using 9801: Io≦200 mA: within ±0.3° = Io value x 0.5%rdg.
Voltage basic wave value: ±2%rdg. Frequency: ±1%rdg.±1dgt.
