Item | TOS9303LC | ||
---|---|---|---|
Voltage conversion | Displays the estimated current converted with the preset supply voltage (Conv Voltage), based on the voltage supplied to the EUT and the measured current. (This is invalid in meter mode.) | ||
Setting range | 80.0 V to 300.0 V, OFF | ||
Resolution | 0.1 V | ||
Power supply line polarity selection | Set the polarity of the power supply line to supply to the EUT to positive or negative. | ||
Single fault mode (Condition) selection | Set the EUT single fault mode to normal, neutral line disconnection (Fault Neu), or protective ground wire disconnection (Fault PE). | ||
Ground check | In the touch current test between the enclosure and power supply line, if the EUT enclosure is grounded, Contact-FAIL occurs. | ||
Measurement check | Checks the measurement function by shorting across the A and B terminals. If an error is found, the protection function is activated. | ||
Supply voltage measurementAC LINE (EUT) | Measurement range | 80.0 V to 250.0 V | |
Resolution | 0.01 V | ||
Accuracy | ±(3 % of reading + 1 V) | ||
Supply current measurementAC LINE (EUT) | Measurement range | 0.1 A to 15.00 A | |
Resolution | 0.001 A | ||
Accuracy | ±(5 % of reading + 30 mA) | ||
Power measurement(active power) | Measurement range | 10 W to 1500 W | |
Accuracy | ±(5 % of reading + 8 W) (with the supply voltage at 80 V or more, at a load power factor of 1) | ||
Voltage measurement across the A and B terminals | Measurement range | DC | 10.00 V to 300.0 V |
RMS | 10.00 V to 300.0 V | ||
Peak | 15.00 V to 430.0 V | ||
Input impedance | Approx. 40 MΩ | ||
Accuracy *1 | ±(3 % of reading + 2 V) (measurement range fixed to AUTO) | ||
SELV detection | Set a voltage for detecting SELV. When the value is exceeded, the DANGER LED lights. | ||
Setting range | 10.0 V to 99.9 V, OFF | ||
Resolution | 0.1V | ||
Measurement terminal | Rated voltage | Between the A and B terminals | 250 V |
Between the terminals and chassis | 250 V | ||
Rated current | 100 mA | ||
Measurement category | CAT-II | ||
Valid terminal display | Terminals valid for measurement are indicated on the display. | ||
110% terminal | Terminal for supplying 110% voltage of the AC line. | ||
Power supply for the EUT | Nominal voltage range | 100 V to 240 V, 50 Hz/60 Hz | |
Input voltage range (allowable voltage range) | 85 Vac to 250 Vac | ||
Rated output capacity | 1500 VA | ||
Maximum operating current | 15 A (Overcurrent protection is activated at approximately 15.7 A.) | ||
Inrush current | 70 Apeak max. (within 20 ms) |
*1 If voltage is measured with the A and B terminals open, measurements will be easily affected by induced voltage.
