Installation

Unpack and inspect contents. Ensure all components are present.

Insert battery: Open battery compartment, install 9V battery.
Connect test leads: Insert black lead into COM jack, red lead into VΩmA jack.
Power on: Turn function dial to any position except OFF.
Test operation: Set to continuity, touch probes - should hear beep.

WARNING! Do not use if meter or leads are damaged. Ensure proper battery installation.

First-Time Setup

Power on multimeter; verify display shows all segments briefly.

Select measurement function: Turn dial to desired measurement type.
Connect probes: Ensure correct jack selection for measurement.
Take reading: Apply probes to circuit/component.
Use data hold: Press HOLD button to freeze display reading.

CAUTION! Always start with highest range when measuring unknown values.

Controls and Settings

Function Dial Positions: OFF, V⎓ (DC voltage), V~ (AC voltage), A⎓ (DC current), Ω (resistance), •))) (continuity/diode).

Buttons: HOLD (data hold), SELECT (function toggle), POWER (on/off).

Display Symbols: AC/DC indicators, low battery, overflow, hold, auto-ranging. Jacks: COM (common), VΩmA (voltage/resistance/current up to 200mA), 10A (current up to 10A).

Connecting Test Leads

Always connect black lead to COM jack. Red lead position depends on measurement:

Voltage/Resistance/Continuity: Red lead in VΩmA jack.
Current (<200mA): Red lead in VΩmA jack.
Current (200mA-10A): Red lead in 10A jack.
Turn function dial to OFF when not in use.

Tip: Ensure leads are fully inserted and not damaged before use.

Taking Measurements

Supports voltage, current, resistance, continuity, diode tests.

DC Voltage: Set to V⎓, connect parallel to circuit, observe polarity.
AC Voltage: Set to V~, connect parallel to circuit.
DC Current: Set to A⎓, connect in series with circuit, use correct jack.
Resistance: Set to Ω, ensure circuit is de-energized, connect across component.
Continuity: Set to •))), circuit must be de-energized, buzzer sounds for continuity.
Diode Test: Set to •))), red lead to anode, black to cathode.
Data Hold: Press HOLD to freeze reading for recording.
Auto Power Off: Meter turns off after 15 minutes of inactivity.

WARNING! Never measure voltage with leads in current jacks. Do not exceed rated voltages.

Safety Features

Overload Protection: Fused protection in current measurement modes. Safety Compliance: Meets IEC 61010-1 CAT II 600V standards. High Voltage Warning: Do not use on circuits >600V AC/DC.

Care & Cleaning

Remove battery when not in use for extended periods. Clean with dry cloth only; no solvents.

CAUTION! Do not use abrasive cleaners. Store in dry place away from extreme temperatures.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No display	Dead battery	Replace 9V battery.
Inaccurate readings	Low battery/leads	Replace battery; check/test leads.
Display shows "1" or "OL"	Overrange	Select higher range.
Continuity buzzer not working	Circuit energized/high resistance	De-energize circuit; resistance may be >30Ω.
Meter turns off unexpectedly	Auto power off	Turn dial to OFF then back to function.
Fuse blown	Overcurrent	Replace with correct rating fuse (F200mA/250V).

Reset: Remove battery for 30 seconds, then reinstall.
