6. Ntuziaka ọrụ
6.1 Gbanyụọ/ gbanyụọ
To power on the meter, rotate the rotary switch from the 'OFF' position to any desired measurement range (e.g., 60A, 20mA, 2mA). To power off, rotate the switch back to the 'OFF' position.
6.2 AC Leakage Current Measurement
- Select the appropriate AC current range (60A, 20mA, or 2mA) using the rotary switch. Start with the highest range if the current value is unknown.
- Mepee clamp agba site na ịpị ihe mkpali ahụ.
- Enclose the single conductor (not multiple conductors) through which the leakage current is to be measured within the clamp agba. Hụ na agba ahụ emechiela nke ọma.
- Read the current value displayed on the LCD. If the reading is too low for the selected range, switch to a lower range for better resolution.
6.3 Data Jide Ọrụ
Press the 'HOLD' button to freeze the current reading on the display. Press the 'HOLD' button again to release the reading and resume live measurement.
6.4 Gbanyụọ ike akpaaka
The meter is equipped with an Auto Power Off feature to conserve battery life. If no operation is performed for approximately 15 minutes, the meter will automatically power off. To reactivate the meter, rotate the rotary switch to 'OFF' and then back to a measurement range, or press any button.

7.2 nnọchi batrị
When the low battery indicator appears on the display, replace the batteries as described in Section 5.1. Always use two new LR44 1.5V batteries.
7.3 Nchekwa
If the meter is not to be used for an extended period, remove the batteries to prevent leakage and store the meter in a cool, dry place away from direct sunlight.
