Instrucțiuni de operare
The HT118E features auto-ranging, simplifying measurements by automatically selecting the correct range.
Operare generala:
- Pornire/Oprire: Rotate the dial from "OFF" to any desired function to power on. Rotate back to "OFF" to power off. The device also features auto power-off after a period of inactivity.
- Selectarea funcției: Turn the rotary dial to the desired measurement function. The LED lights on the input jacks will illuminate to guide you on where to insert the test leads.
- Iluminare de fundal LCD: Press the backlight button (sun icon) to illuminate the display for use in dimly lit environments.
- Lanternă: Press and hold the backlight button to activate the flashlight located on the back of the device.

Funcții specifice de măsurare:
1. AC/DC Voltage Measurement (V~ / V=)
Pentru a măsura voltage, connect the red test lead to the VΩHz input and the black test lead to the COM input. Select the appropriate voltage range on the rotary dial (V~ for AC, V= for DC). The orange backlight illuminates when voltage depășește 80V.

2. AC/DC Current Measurement (A~ / A=)
For current measurement, connect the red test lead to the mA/µA or 10A input (depending on expected current) and the black test lead to the COM input. Select the current function on the dial. The orange backlight illuminates when current exceeds 1A.

3. Măsurarea rezistenței (Ω)
Connect test leads to VΩHz and COM inputs. Select the resistance function (Ω) on the dial. The multimeter will display the resistance value.

8. Test de continuitate (Ω))))
Connect test leads to VΩHz and COM inputs. Select the continuity function on the dial. A continuous beep indicates a complete circuit (low resistance).
9. Vol. fără contacttage (NCV) / Live Wire Test
Select the NCV/Live function on the dial. Place the top of the multimeter near a live wire. The device will detect AC voltage without direct contact. Weak AC signals will cause green indicator lights to illuminate, while strong AC signals will cause red indicator lights to illuminate and an alarm to sound.

Întreţinere
curatenie:
Ștergeți suprafața c a multimetruluiasing cu anunțamp lavetă. Nu utilizați substanțe de curățare abrazive sau solvenți. Asigurați-vă că dispozitivul este oprit și deconectat de la orice circuit înainte de curățare.
Depozitare:
When not in use for extended periods, remove the batteries to prevent leakage. Store the multimeter in its durable carrying case in a cool, dry place away from direct sunlight and extreme temperatures.
Depanare
- Fără afișaj/alimentare:
- Verificați instalarea bateriilor și asigurați-vă că bateriile nu sunt descărcate. Înlocuiți-le dacă este necesar.
- Ensure the rotary dial is set to an active function, not "OFF".
- Citiri inexacte:
- Verify test leads are correctly inserted into the appropriate input jacks for the selected function.
- Ensure good contact between test probes and the circuit/component.
- Check if the batteries are low (indicated by the low battery icon on the display). Low batteries can affect accuracy.
- Afișajul arată „OL” (Suprasarcină):
- The measured value exceeds the selected range. For auto-ranging meters, this usually means the value is beyond the meter's maximum capability for that function.
- Ensure you are not attempting to measure current in a voltage input, or vice-versa, which can damage the meter.
