APPA 158B Bluetooth Clamp-On Meter

Product Information

The APPA 158B Power Clamp Meter is a Bluetooth-enabled clamp-on meter designed for measuring both direct and alternating current.
The meter is protected by double or reinforced insulation and conforms to EU directives. The product comes with a user manual, test leads, a temperature probe, a carrying case, and a battery.
The meter has an APO (Auto Power Off) function and can display measurement results in AC only with RMS value or DC value, depending on whichever is greater.

Product Usage Instructions

1. Before using the meter, read the safety information and operating instructions carefully.
2. When measuring voltage, do not attempt to measure anything that might exceed 1000 V DC or AC RMS. If the measured voltage is greater than 30 V DC or AC RMS, the display will show the symbol.
3. When measuring current, do not hold the meter across the tactile barrier. Do not clamp on any conductor while the meter power is on.
4. Press the power button for 2 seconds to turn on/off the meter.
5. The APO function can be disabled by pressing the OK button while turning on the meter from the OFF position.
6. Use the arrow keys to move the blinking cursor to the target icon, and then press the OK button or hold it for more than 2 seconds to execute the function.
7. Before making measurements, observe the rules of warnings and cautions. When connecting test leads to the DUT (Device Under Test), connect the common test lead before connecting the live lead; when removing the test leads, remove the test live lead before removing the common test lead.
8. Periodically wipe the meter’s case with a dry cloth and detergent. Do not use abrasives or solvents.
9. If the meter needs to be repaired or serviced, it should only be performed by qualified personnel as it contains no user-serviceable parts.
