4. Setup

4.1 Battery Installation

Both multimeters require battery installation before first use.

• SZ301 Multimeter: Requires 2x 1.5V AA batteries. Open the battery compartment on the back, insert batteries observing polarity, and close the cover securely.
• A3005 Pen Type Multimeter: Requires 2x 1.5V AAA batteries. Open the battery compartment, insert batteries observing polarity, and close the cover securely.

4.2 Connecting Test Leads (SZ301)

For most measurements with the SZ301, test leads must be connected to the appropriate input jacks.

• Insert the red test lead into the VΩmA+ jack.
• Insert the black test lead into the COM (common) jack.
• For high current measurements (10A), insert the red test lead into the 10A jack.

5. Operating Instructions

5.1 General Operation (SZ301)

• Power On/Off: Rotate the dial from the OFF position to any desired function to power on. Rotate back to OFF to power off.
• Function Selection: Use the rotary dial to select the desired measurement function (e.g., V~ for AC Voltage, V- for DC Voltage, Ω for Resistance).
• HOLD Function: Press the 'HOLD' button to freeze the current reading on the display. Press again to release.
• SEL Function: Press the 'SEL' button to switch between different modes within a single dial position (e.g., AC/DC voltage, Diode/Continuity).

5.2 AC Voltage Measurement (SZ301)

To measure AC voltage:

1. Set the rotary dial to the V~ (AC Voltage) range.
2. Connect the red test lead to the VΩmA+ jack and the black test lead to the COM jack.
3. Carefully touch the test probes to the points where AC voltage is to be measured (e.g., wall outlet terminals).
4. Read the voltage value on the display.

5.3 DC Voltage Measurement (SZ301)

To measure DC voltage:

1. Set the rotary dial to the V- (DC Voltage) range.
2. Connect the red test lead to the VΩmA+ jack and the black test lead to the COM jack.
3. Touch the red probe to the positive terminal and the black probe to the negative terminal of the DC source.
4. Read the voltage value on the display.

5.4 AC/DC Current Measurement (SZ301)

To measure current, the multimeter must be connected in series with the circuit. Ensure the circuit is de-energized before connecting the multimeter.

1. Set the rotary dial to the appropriate current range (e.g., 200mA, 10A).
2. Connect the red test lead to the mA or 10A jack and the black test lead to the COM jack.
3. Open the circuit where current is to be measured and connect the multimeter in series.
4. Energize the circuit and read the current value.

5.5 Resistance, Continuity, and Diode Measurement (SZ301)

These functions are typically performed on de-energized circuits.

• Resistance (Ω): Set the dial to the Ω range. Connect probes across the component.
• Continuity: Set the dial to the continuity mode (often shared with diode or resistance, use SEL to switch). A beep indicates continuity.
• Diode: Set the dial to the diode mode. Connect probes across the diode to measure forward voltage drop.

5.6 Pen Type Multimeter (A3005) Functions

The A3005 offers quick and convenient testing capabilities.

• AC/DC Voltage: Touch the probe to the test point. The display will show the voltage.
• NCV (Non-Contact Voltage) Sensing: Bring the tip of the pen close to an AC voltage source without direct contact. The device will indicate the presence of voltage through audible and visual alarms.

• Live Wire Detection: Use the dedicated live wire detection function to identify live conductors.

6. Maintenance

6.1 Battery Replacement

When the low battery indicator appears on the display, replace the batteries promptly to ensure accurate readings.

• Power off the device.
• Open the battery compartment cover on the back of the device.
• Remove the old batteries and dispose of them properly.
• Insert new batteries (2x 1.5V AA for SZ301, 2x 1.5V AAA for A3005) observing correct polarity.
• Close the battery compartment cover securely.

6.2 Cleaning

To clean the device, wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is powered off and disconnected from any circuits before cleaning.

6.3 Storage

If the device is not to be used for an extended period, remove the batteries to prevent leakage and store the multimeter in a cool, dry place away from direct sunlight and extreme temperatures.
