Additional Information:
Application software available for download to enhance functionality via USB interface. Designed for use under qualified supervision, not for home or general consumer use.

Additional Specifications:

Frequency Accuracy: At 10 kHz, the accuracy is ±(5.0% of reading + 0.5 mA).
Input Characteristics: Input resistance is 1 MΩ±1%, and input capacitance is less than 200 pF.
Common Mode Rejection Ratio: At frequencies up to 10 kHz, it is 60 dB or greater; between 10 kHz and 1 MHz, it is 40 dB or greater.

Judgement Function:

Method: Pass/fail judgement using a window comparator mode with set upper and lower current limits.
Display: U-FAIL for currents above the upper limit, L-FAIL for currents below the lower limit, with visual and audible indicators.
PASS Hold: Retention time for a PASS judgement can be set between 0.2 s to 10.0 s or to HOLD.

Measurement Ranges:

Current Ranges:
- Range 1: DC/RMS from 30 μA to 600 μA, PEAK from 50 μA to 850 μA.
- Range 2: DC/RMS from 151 μA to 6.00 mA, PEAK from 213 μA to 8.50 mA.
- Range 3: DC/RMS from 1.51 mA to 30.0 mA, PEAK from 2.13 mA to 90.0 mA.
Voltage Measurement: DC/RMS from 10.000 V to 300.0 V, PEAK from 15.000 V to 430.0 V with an accuracy of ±(3% of reading + 2V).

Safety and Detection:
SELV Detection: The SELV setting range is 10 V to 99 V, with a DANGER lamp activation if exceeded.

Timer and Test Execution:

Timer Settings: Test wait time from 0 s to 999 s, and test time from 1 s to 999 s with an OFF function.
Execution Modes: AUTO mode for automatic execution of up to 100 steps, and MANUAL mode for independent execution.

Memory and Results:

Test Conditions: Up to 100 sequence programs can be saved in both AUTO and MANUAL modes.
Test Results: Option to save judgement results, with storage for up to 50 programs or tests.

Additional Notes:
Warm-up time must be 30 minutes or longer. Reading (rdng) refers to the measured value, and set refers to the set value. Specific conditions apply to custom-made or modified products and those with CE marking.
