①Measuring Input
| Code | Measuring Range | Input Resistance | Accuracy *1 | Overload *3 |
|---|---|---|---|---|
| 23 | 999.9 mV rms | 1 MΩ | ±(0.2% of rdg. + 10 digit) | AC 100 V |
| 24 | 9.999 V rms | 1 MΩ | AC 200 V | |
| 25 | 99.99 V rms | 10 MΩ | AC 250 V | |
| 26 | 300.0 V rms | 10 MΩ | AC 300 V | |
| 35 | 99.99 mA rms | 1 Ω | ±(0.3% of rdg. + 10 digit) | AC 500 mA |
| 36 | 999.9 mA rms | 0.1 Ω *2 | ±(0.5% of rdg. + 10 digit) | AC 2 A |
| 37 | 2.000 A rms |
- *1 Accuracy:
- Defined at 23 ± 5°C, 45 to 75% RH.
Defined with sine wave of input frequency 40 Hz to 1 kHz, and at 4% or more of the rated input. - *2
- External shunt resistor 0.1 Ω
- Temperature coefficient:
- ± 300 ppm/°C. Defined over an operating temperature range of 0 to 50°C
- Crest factor:
- 4 (peak 500 V for -26, peak 3 A for -36 and -37)
- *3 Overload (1min):
- Applying a voltage or current that exceeds the excessive input range to the input may damage the equipment.
- Note:
- The display will show 0, when the input is less than 0.1%of the rated input.
