Zvikamu Zvikuru:

Chiratidziro cheLCD: Inoratidza kuyerwa kwezviyero.
Rotary Switch: Selects measurement functions and ranges.
Input Jacks: For connecting test leads (typically COM, VΩmA).
Miedzo Inotungamira: Red (positive) and Black (negative/common) leads with probes.

4. Setup

4.1 Kuiswa kwebhatiri

The multimeter requires a 9V battery (not included). To install:

Tsvaga bhatiri remukati chivharo kuseri kweiyo multimeter.
Remove the screw(s) securing the cover and lift it off.
Connect a 9V battery to the battery clips, observing correct polarity (+ and -).
Isa bhatiri mukamuri uye wotsiva chivharo, uchichengetedza ne screw(s).

4.2 Kubatanidza Miedzo Inotungamira

Batanidza bvunzo inotungamira kune akakodzera ekuisa jacks:

Isa mutema bvunzo lead mu COM Jeki (yakajairika).
Isai dzvuku bvunzo lead mu VΩmA jack for voltage, kuramba, uye kuyerwa kwemagetsi.

5. Operating Instructions

Before making any measurement, ensure the test leads are correctly connected and the rotary switch is set to the desired function and range.

5.1 Kuyera DC Voltage (DCV)

The multimeter offers 4 DCV ranges: 2V, 20V, 200V, 500V.

Set the rotary switch to the desired DCV range (e.g., 20V for typical battery checks). If the voltage haizivikanwe, tanga nehukuru hwepamusoro (500V) wodzikisa sezvinodiwa.
Connect the red test probe to the positive (+) side of the circuit and the black test probe to the negative (-) side.
Verenga bhukutage kukosha pane LCD kuratidza.

5.2 Kuyera AC Voltage (ACV)

The multimeter offers 2 ACV ranges: 200V, 500V.

Set the rotary switch to the desired ACV range (e.g., 200V or 500V for household outlets).
Batanidza ma probe ekuyedza pa AC voltage source.
Verenga bhukutage kukosha pane LCD kuratidza.

5.3 Measuring DC Current (DCA)

The multimeter offers 3 DCA ranges: 2mA, 20mA, 200mA.

YAMBIRO: Usambofa wakabatanidza multimeter panguva imwe chete nevoltage source when measuring current. This can damage the meter and the circuit.
Set the rotary switch to the desired DCA range.
Open the circuit where you want to measure current.
Connect the multimeter in series with the circuit, ensuring the current flows through the meter. The red probe connects to the higher potential side, and the black probe to the lower potential side.
Verenga kukosha kwazvino paLCD kuratidza.

5.4 Measuring Resistance (Ohms)

The multimeter offers 5 Ohms ranges: 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ.

YAMBIRO: Ensure the circuit or component under test is completely de-energized before measuring resistance.
Set the rotary switch to the desired Ohms range.
Batanidza ma test probes pakati pechikamu chaunoda kuyera kuramba kwacho.
Verenga kukosha kwekupikisa pane LCD kuratidza.

5.5 Diode Check

This function allows you to test diodes for proper operation.

Set the rotary switch to the Diode Check symbol (usually a diode icon).
Connect the red test probe to the anode of the diode and the black test probe to the cathode. A forward voltage drop (e.g., 0.5V to 0.7V for silicon diodes) should be displayed.
Reverse the probes. The display should show "OL" (Overload) or a very high resistance, indicating an open circuit. If both directions show a reading or "OL", the diode may be faulty.

6.2 Kutsiviwa kwebhatiri

When the battery low indicator appears on the display, replace the 9V battery as described in the "Battery Installation" section (4.1). Always use a fresh 9V alkaline battery.

6.3 Fuse Kutsiva

If the current measurement function stops working, the fuse may need replacement. Refer to the specifications for the correct fuse type. Fuse replacement typically involves opening the back casing of the multimeter. If unsure, consult a qualified technician.
