2. Safety Information

WARNING: To avoid electric shock or personal injury, please read and understand all safety information before using this meter.

• Always inspect the meter for damage before use. Do not use if damaged.
• Do not apply more than the rated voltage, as marked on the meter, between the terminals or between any terminal and ground.
• Use caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC. These voltages pose a shock hazard.
• Keep fingers behind the finger guards on the clamp jaws during measurement.
• Do not operate the meter around explosive gas, vapor, or dust.
• Ensure the battery cover is securely closed before operation.
• Replace batteries immediately when the low battery indicator appears.

4. Setup

4.1 Battery Installation

The meter requires two 1.5V AAA batteries for operation. Follow these steps to install or replace batteries:

1. Ensure the meter is powered off.
2. Locate the battery compartment on the back of the meter.
3. Use a screwdriver to open the battery compartment cover.
4. Insert two 1.5V AAA batteries, observing the correct polarity (+ and -) as indicated inside the compartment.
5. Replace the battery compartment cover and secure it with the screw.

5. Operating Instructions

5.1 Power On/Off

Press the POWER button to turn the meter on. The meter will automatically enter auto-ranging mode. To turn off the meter, press and hold the POWER button, or it will automatically power off after a period of inactivity.

5.2 AC Leakage Current Measurement

The SK-2060 is specifically designed for measuring micro AC leakage currents. Follow these procedures:

1. Detecting Leakage Current on the Grounding Line:

   Open the clamp trigger and clamp the meter around the grounding line only. The LCD will display the value of the leakage current on the grounding line.

2. Detecting Leakage Current of Unbalanced Work Power Line:

   Open the clamp trigger. For a single-phase alternating current (AC) system, clamp the power line and the neutral line together (Figure 5, Diagram 1). For a three-phase three-wire system, clamp all three phase lines together (Figure 5, Diagram 2). For a three-phase four-wire system, clamp all three phase lines and the neutral line together (Figure 5, Diagram 3). If there is a ground wire, it cannot be clamped together with the working power lines.

   Note: Many factories and companies use a three-phase five-wire system. In addition to the three phase wires, there is a working zero line and a protective zero line (grounding). For leakage current inspection, the grounding line must be clamped individually and not together with the four working power lines.

5.3 Data Hold Function

Press the HOLD button to freeze the current reading on the display. Press it again to release the hold and resume live measurements.

5.4 Range Selection (Auto/Manual)

The meter defaults to auto-ranging. To switch to manual ranging, press the RANGE button. Each press will cycle through available ranges. To return to auto-ranging, press and hold the RANGE button.

5.5 Automatic Power Off

To conserve battery life, the meter will automatically power off after approximately 15 minutes of inactivity. To disable this feature temporarily, press and hold the HOLD button while turning the meter on. The auto power-off function will be re-enabled the next time the meter is powered on normally.

6. Maintenance

6.1 Cleaning

Wipe the meter with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the meter is completely dry before storage or use.

6.2 Battery Replacement

Refer to Section 4.1 for battery installation and replacement instructions. Always use two new 1.5V AAA batteries. Remove batteries if the meter is not used for an extended period to prevent leakage.

6.3 Storage

Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided carrying case for protection.

7. Troubleshooting

• No Display / Faint Display: Check battery installation and replace batteries if necessary. Ensure the meter is powered on.
• Inaccurate Readings: Ensure the wire is properly centered within the clamp jaws. Verify the correct measurement mode and range are selected. Check for external electromagnetic interference.
• Meter Does Not Turn On: Ensure batteries are correctly installed and have sufficient charge.
