5. Operating Instructions

5.1 Controls and Display

Figure 3: Button Introduction

• Rotary Switch: Selects the desired measurement function (e.g., DC/AC Power, AC/DC Clamp, V/Hz, Temperature).
• HOLD Key: Freezes the current reading on the display. Press again to release.
• SELECT Key: Toggles between different measurement modes within a function (e.g., AC/DC current, °F/°C).
• LIGHT Key: Activates the backlight for the LCD display.
• CLEAR Key: Clears saved data or resets certain functions.
• MAX/MIN Key: Records the maximum and minimum values during a measurement.
• LCD Display: Shows measurement readings, units, and function indicators.

5.2 Measurement Functions

The HP-870P offers a comprehensive set of measurement capabilities:

5.2.1 AC/DC Current Measurement (Clamp)

Use the clamp jaws to measure current without breaking the circuit. Rotate the rotary switch to the "DC/AC CLAMP" position. Open the jaws and clamp around a single conductor. The display will show the current reading.

5.2.5 Other Functions

• Data Hold: Press the HOLD button to freeze the current reading.
• Backlight: Press the LIGHT button to illuminate the display for use in low-light conditions.
• MAX/MIN: Press the MAX/MIN button to capture the highest and lowest readings during a measurement session.

6. Maintenance

• Cleaning: Wipe the meter with a dry, soft cloth. Do not use abrasives or solvents.
• Storage: When not in use for extended periods, remove the batteries to prevent leakage. Store the meter in its carrying case in a cool, dry place.
• Calibration: For professional accuracy, periodic calibration by a qualified technician is recommended.

7. Troubleshooting

If the meter does not function correctly, check the following:

• No Display/Faint Display: Check battery installation and charge level. Replace batteries if necessary.
• Incorrect Readings: Ensure the correct function is selected on the rotary switch. Verify test leads are properly connected and making good contact. Ensure the circuit under test is de-energized for resistance, diode, or continuity measurements.
• No Response: Try turning the meter off and on again. If the issue persists, contact customer support.
