HT10 CAT IV 2 Pole Multimeter User Manual

1. Introduction

The HT10 is a two-pole multifunction tester designed for practical, quick, and functional measurements. Its narrow and long structure allows for measurements in various operating conditions. This device performs AC/DC voltage measurements with polarity indication, continuity tests with a buzzer, and phase sequence detection using LED indications and a digital display. The HT10 also measures AC voltage with low input impedance and performs RCD trip testing. It includes a white LED torch for use in dimly lit environments and complies with safety standards IEC/EN61243-3:2014/VDE 0682, IEC/EN61010-1, and IEC/61010-2-030, ensuring safe and reliable operation.

The instrument indicates dangerous voltage presence even without battery power or in case of main circuit failure. With a protection class of IP64 (dust and splash-proof) and molded soft rubber grips, the HT10 is a heavy-duty instrument suitable for demanding domestic or industrial applications.

5. Setup and Battery Installation

The HT10 is powered by batteries. Ensure fresh batteries are installed for optimal performance and accurate readings.

1. Locate the battery compartment on the back of the instrument.
2. Use a suitable screwdriver to open the battery compartment cover.
3. Insert the required batteries, observing the correct polarity (+/-) as indicated inside the compartment.
4. Replace the battery compartment cover and secure it with the screw.
5. Before first use, or after battery replacement, it is recommended to test the instrument on a known voltage source to confirm proper operation.

6. Operating Instructions

6.1. AC/DC Voltage Measurement

1. Ensure the test leads are securely connected to the instrument.
2. Touch the L1 and L2 probes to the points where voltage is to be measured.
3. The instrument will automatically detect AC or DC voltage and display the reading on the digital screen.
4. LED indicators will illuminate corresponding to the detected voltage level (e.g., 12V, 24V, 50V, 120V, 230V, 400V, 690V, 1000V).
5. For DC voltage, polarity will be indicated.

6.2. Continuity Test

1. Ensure the circuit under test is de-energized.
2. Press the continuity test button (often indicated by an Ohm symbol or speaker icon).
3. Touch the L1 and L2 probes to the two points of the circuit to be tested for continuity.
4. A buzzer will sound and/or an LED will illuminate if continuity is detected (low resistance).

6.3. Phase Sequence Detection

1. Connect the L1 and L2 probes to the phases of a three-phase system.
2. The instrument will indicate the phase rotation (L or R) using dedicated LEDs.

6.4. RCD Trip Test

1. Connect the HT10 to an RCD-protected circuit.
2. Activate the RCD trip test function (refer to specific button on device).
3. The instrument will draw a small current to trip the RCD. This function only confirms tripping, not trip time or current.

6.5. Using the LED Torch

The HT10 features an integrated white LED torch for illuminating dark work areas. Activate the torch using the dedicated button (often indicated by a light bulb icon).

6.6. Data HOLD Function

Press the HOLD button to freeze the current reading on the display. Press it again to release the hold and resume live readings.

7. Maintenance and Care

• Cleaning: Clean the instrument regularly with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the instrument in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
• Battery Replacement: Replace batteries promptly when the low battery indicator appears to ensure accurate measurements.
• Inspection: Periodically inspect the instrument and test leads for any signs of damage, such as cracks, frayed insulation, or exposed wiring. Do not use if damaged.
• Calibration: For professional use, periodic calibration by a qualified service center is recommended to maintain accuracy.
