Note: Ensure batteries are installed correctly to prevent damage to the device.
5. Operasyon Enstriksyon
5.1 KAIWEETS Digital Multimeter HT118A Operation
The HT118A features auto-ranging for most functions, simplifying operation. Connect the test leads to the appropriate input jacks (COM and VΩmA for most measurements, 10A for high current).
Fonksyon Mezi:
- AC / DC Voltage (V): Turn the dial to V~ (AC) or V- (DC). The multimeter will auto-range.
- AC/DC Current (A, mA): Turn the dial to A~ (AC) or A- (DC) for high current, or mA~ (AC) or mA- (DC) for low current. Ensure test leads are connected to the correct current input jack (10A or mA).
- Rezistans (Ω): Turn the dial to Ω.
- Continuity (•))): Turn the dial to •))). A buzzer will sound for low resistance.
- Diode (→|): Turn the dial to →|.
- Capacitance (∔): Turn the dial to ∔.
- Frekans (Hz): Can be measured in conjunction with voltage or current functions, or as a standalone function.
- Tanperati (°C/°F): Turn the dial to °C/°F. Connect the K-type thermocouple to the VΩmA and COM jacks.
- NCV (Vol ki pa gen kontaktage): Turn the dial to NCV. Bring the top of the multimeter near an AC voltage source to detect its presence without direct contact.
- Live Wire Detection: Turn the dial to Live. Insert the red test lead into the VΩmA jack and touch the probe to the wire. The display will indicate if it's a live wire.
