Figura 1: Frontal view of the HT64 Digital Multimeter. The device features an orange casing with a black central panel. The large graphic display shows "264.8 V~Hz" and "60.0 Hz". Below the display are four function buttons (F1, F2, F3, F4) and four navigation buttons (GRAPH, MODE, MENU, MAX). A large rotary dial is centrally located, surrounded by various measurement settings such as 10A, mA, µA, V~Hz, mV~, Hz%, Ω, CAP, Temp, and OFF/CHG. Input jacks are visible at the bottom for 10A, 800mA, and COM connections, along with a VHz% / CAP / Temp input.
4. Configuració
4.1. Instal·lació i càrrega de la bateria
The HT64 multimeter comes with a rechargeable Lithium Ion battery. Before first use, ensure the battery is fully charged using the provided charging dock.
- Localitzeu el compartiment de la bateria a la part posterior del dispositiu.
- Insert the BAT64 rechargeable battery, ensuring correct polarity.
- Tanqueu el compartiment de la bateria de manera segura.
- Connect the HT64 to the charging dock and plug the dock into a power source. The display will indicate charging status.
4.2. Engegada inicial
To power on the device, rotate the central dial from the "OFF/CHG" position to any desired measurement function (e.g., V~Hz). The display will illuminate.
5. Instruccions de funcionament
5.1. Rotary Dial Functions
The large central rotary dial is used to select the primary measurement function. Each position corresponds to a specific type of measurement:
- OFF/CHG: Powers off the device and enables charging.
- V~Hz: Measures AC Voltage and Frequency.
- V-: Measures DC Voltage.
- mV~: Measures AC Millivoltage.
- Hz%: Measures Frequency and Duty Cycle.
- Ω CAP Temp: Measures Resistance, Capacitance, and Temperature.
- µA Hz%: Measures Microamperes (AC/DC) and Frequency/Duty Cycle.
- mA Hz%: Measures Milliamperes (AC/DC) and Frequency/Duty Cycle.
- 10A Hz%: Mesures Amperes (AC/DC) up to 10A and Frequency/Duty Cycle.
5.2. Front Panel Buttons
The HT64 features several buttons for advanced functions and navigation:
- F1, F2, F3, F4: Context-sensitive function keys, their purpose changes based on the selected mode and is indicated on the display.
- GRÀFIC: Activates the graphing function for visualizing measurement trends.
- Mode: Toggles between different sub-functions within a rotary dial setting (e.g., AC/DC, Resistance/Capacitance/Temperature).
- MENÚ: Accesses the main menu for settings and configurations.
- MÀXIM: Displays the maximum recorded value during a measurement session.
- GAMMA: Alterna entre els modes de rang automàtic i de rang manual.
- HOLD REL:
- MANTENIR: Congela la lectura actual de la pantalla.
- REL (Relative): Measures the difference between the current reading and a stored reference value.
5.3. Terminals d'entrada
Connect test leads to the appropriate input terminals based on the measurement type:
- COM: Terminal comú per a totes les mesures.
- VHz% / CAP / Temp: Input for Voltage, Frequency, Resistance, Capacitance, and Temperature measurements.
- mA / µA: Input for Milliamperes and Microamperes measurements (Max 800mA).
- 10A: Entrada per Amperes measurements up to 10A.
Safety Warning: Always ensure test leads are connected to the correct terminals for the selected measurement function to prevent damage to the meter or personal injury. Observe the CAT IV 600V and CAT III 1000V ratings.
6. Manteniment
6.1. Neteja
To maintain the accuracy and longevity of your HT64, keep it clean. Use a soft, damp cloth with mild detergent to wipe the casing. Do not use abrasive cleaners or solvents. Ensure the device is powered off and disconnected from any circuits before cleaning.
6.2. Cura de la bateria
To maximize battery life, charge the battery regularly. If the device will not be used for an extended period, it is recommended to fully charge the battery and store the device in a cool, dry place. Avoid extreme temperatures.
6.3. Substitució de fusibles
The HT64 is fused for protection. If the current measurement function stops working, the fuse may need replacement. Refer to the detailed service manual for fuse specifications and replacement procedures. Fuse replacement should only be performed by qualified personnel.
7. Solució De Problemes
This section provides solutions to common issues you might encounter with your HT64 multimeter.
| Problema | Causa possible | Solució |
|---|---|---|
| El dispositiu no s'encén. | Low or depleted battery. Incorrect battery installation. | Charge the battery using the charging dock. Ensure the battery is correctly inserted. |
| No hi ha lectura ni es mostra "OL" (sobrecàrrega). | Incorrect function selected. Test leads not properly connected. Measurement exceeds range. Blown fuse (for current measurements). | Verify the rotary dial is set to the correct function. Ensure test leads are securely connected. Select a higher range if available or check fuse for current measurements. |
| Lectures inexactes. | Poor test lead connection. Environmental interference. Device needs calibration. | Check test lead connections. Move away from strong electromagnetic fields. Contact HT Instruments for calibration services. |
