5.1 Kuiswa kwebhatiri

The multimeter requires 2 x 1.5V AAA batteries (not included). To install or replace batteries:

1. Ensure the multimeter is powered off and test leads are disconnected.
2. Tsvaga chivharo chebhatiri kuseri kwemudziyo.
3. Shandisa screwdriver kuvhura kamuri yebhatiri.
4. Insert two 1.5V AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
5. Tsiva chivharo chekamuri yebhatiri uye chengetedza nescuru.

5.2 Kubatanidza Miedzo Inotungamira

Multimeter inouya nemidziyo miviri yekuyedza (tsvuku nenhema). Vabatanidze seizvi:

• Insert the black test lead into the 'COM' (Common) input jack.
• Insert the red test lead into the 'INPUT' jack for most measurements (Voltage, Resistance, Frequency, Continuity, Diode, Capacitance).

6. Operating Instructions

6.1 Simba On/Kudzima

Dzvanya bhatani remagetsi dzvuku (Simba On bhatani) to turn the multimeter on or off. The device features an auto-shutdown function to conserve battery life after a period of inactivity.

6.2 Measurement Modes

The multimeter offers two primary measurement modes:

Figure 5: The multimeter supports both auto identification and manual switching modes.

• Auto Identification Mode: When powered on, the meter defaults to auto identification. In this mode, it automatically detects and measures AC/DC voltage, frequency, resistance, and continuity. Simply connect the test leads to the circuit, and the meter will display the relevant measurement.
• Manual Switch Mode: To access specific functions not covered by auto identification or to manually select a range, press the 'NCV/LIVE' button (or other function buttons if available on your specific model, e.g., FY129C for Diode/Capacitance). This allows you to cycle through AC/DC voltage, frequency, resistance, continuity, LIVE, and NCV.

6.3 Kuyera AC/DC Voltage

1. Connect the black test lead to the 'COM' jack and the red test lead to the 'INPUT' jack.
2. If in auto identification mode, the meter will automatically detect voltage. If in manual mode, select the appropriate AC or DC voltage function.
3. Batanidza tambo dzekuedza dzakafanana pakati pechikamu kana dunhu rinofanira kuyerwa.
