4. Setup
4.1 Installing Test Leads and Temperature Probe
The HP-870P comes with a pair of test leads (red and black) and a temperature probe. Follow these steps to prepare your meter for use:
- Ensure the meter is turned OFF.
- For voltage, resistance, capacitance, or frequency measurements, insert the red test lead into the 'V' input jack and the black test lead into the 'COM' input jack.
- For temperature measurements, insert the temperature probe into the dedicated temperature input jacks (T+ and T-COM).
- For current measurements using the clamp, no test leads are required.
5. Operating Instructions
The HP-870P offers a variety of measurement functions. Always ensure the correct function is selected before taking a measurement.
5.1 AC and DC Current Measurement
To measure AC or DC current, rotate the dial to the corresponding '≈A' (AC current) or 'A' (DC current) position. Clamp the jaws around a single conductor. The display will show the current reading. For DC current, you may need to press and hold the 'SELECT' button to switch to the DC gear.
5.2 AC and DC Voltage Measurement
Rotate the dial to the '≈V/Hz' (AC voltage) or 'V' (DC voltage) position. Connect the test leads to the circuit in parallel. The display will show the voltage reading. Use the 'SELECT' button to toggle between AC and DC voltage if needed.
5.3 Power Measurement (Active, Reactive, Apparent) and Power Factor
Rotate the dial to the 'AC POWER' position for AC power measurements or 'DC kW' for DC power. Use the 'SELECT' button to cycle through Active Power (kW), Reactive Power (kVAr), Apparent Power (kVA), and Power Factor (Cosφ) measurements. Connect the test leads appropriately for voltage and clamp the jaws around the current-carrying conductor.
5.4 Temperature Measurement
Rotate the dial to the '°F/°C' position. Connect the temperature probe to the dedicated jacks. The display will show the temperature reading in either Fahrenheit or Celsius, which can be toggled using the 'SELECT' button.

8. Troubleshooting
If you encounter issues with your HP-870P, please refer to the following common problems and solutions:
- No Display/Faint Display: Check battery levels and replace if necessary. Ensure the meter is turned ON.
- Inaccurate Readings: Verify that the correct function is selected for the measurement. Ensure test leads are properly connected and not damaged. Check for external interference.
- Display Viewing Angle: Due to the special function of the IC, the display viewing angle of the product HP-870P clamp meter has certain limitations. For the convenience of the user, the angle is set to the front 45° angle as the best, but it will have some influence when viewing the screen from above. This is normal, not a product failure.
- Meter Not Responding: Try turning the meter off and on again. If the issue persists, remove the batteries for a few minutes and then reinsert them.
