4. Operating Instructions
Voltage Test (AC/DC)
To measure voltage:
- Ensure the probes are securely connected to the device.
- Connect both probes to the object under test.
- The voltage reading will be displayed on the LCD, and corresponding LEDs will light up to indicate the voltage level and polarity (AC, +DC, -DC).
- A high voltage indicator (LED) will light up if the measured voltage exceeds 50V.
- The auto-hold function will lock the present display value when the L1 and L2 probes disconnect from the measured terminal.

Voltage Test Demonstration:
Video: Demonstration of voltage testing, including polarity indication and auto-hold function.
Continuity Test
To perform a continuity test:
- Press the SELECT key to enter continuity test mode.
- Connect the probes across the circuit or component you wish to test.
- If the on-resistance of the measured object is within the range of 0-550kΩ (±200K), the RXΩ LED indicator will light up and a buzzer will sound.
- In continuity mode, the instrument operates similarly to a self-diagnostic test.
Continuity Test Demonstration:
Video: Demonstration of the continuity test function.
Phase Rotation Test
For three-phase 4-wire AC systems (50Hz-60Hz):
- Connect two probes to the tested object (e.g., phase lines).
- Observe the L and R LEDs:
- If the R LED is on, the L2 test probe is connected to phase B line and the L1 test probe is connected to phase A line.
- If the L LED is on, the L2 test probe is connected to phase A line and the L1 test probe is connected to phase B line.
- The phase voltage will be indicated by the LEDs, and the value displayed on the LCD screen.
Phase Rotation Test Demonstration:

Pen Light Function
Press the 'PEN' button to activate the built-in LED flashlight. This is useful for illuminating work areas in dim or dark environments.

5. Maintenance
Cleaning
To clean the device, wipe it with a dry, soft cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the casing or internal components.
Storage
Store the HP-38A in a dry, cool place, away from direct sunlight and extreme temperatures. If the device will not be used for an extended period, remove the batteries to prevent leakage and damage.
Battery Replacement
The device features a low battery indication. When the battery voltage is lower than 2.4±0.1V, the power indicator will blink or turn off, signaling that the batteries need to be replaced. Refer to the 'Battery Installation' section for detailed steps.

6. Troubleshooting
- No Display/Power:
Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary. - Inaccurate Readings:
Ensure the probes are clean and making good contact with the test points. Verify that the correct measurement mode is selected using the SELECT key. - No Continuity Beep:
Confirm that the resistance of the circuit or component being tested is within the specified range of 0-550kΩ. - LEDs Not Lighting Up:
Check the battery level. Ensure the voltage being measured is within the device's operational range for LED indication.
