2. Safety Information

Always adhere to the following safety precautions to prevent personal injury and damage to the meter:

• Do not exceed the maximum input values for any measurement range.
• Exercise extreme caution when working with voltages above 36V DC or 25V AC RMS, as these can pose a shock hazard.
• Before measuring current, ensure the circuit is de-energized if possible, and always clamp around only one conductor.
• Before measuring resistance or continuity, ensure the circuit is de-energized and all capacitors are discharged.
• Do not operate the meter if it appears damaged or if the test leads are compromised.
• Ensure the battery cover is securely closed before operation.
• Use only the specified test leads and accessories.

3. Getting Started (Setup)

3.1 Battery Installation

The GOLDEN BLUE ST213 requires two AAA batteries (not included) for operation.

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

3.2 Connecting Test Leads

For voltage, resistance, continuity, capacitance, and diode measurements, connect the test leads:

• Insert the red test lead into the "INPUT" jack.
• Insert the black test lead into the "COM" (common) jack.

4. Operation

4.1 Power On/Off and Function Selection

• To power on the meter, long press the "SEL" button.
• To switch between measurement functions (e.g., AC/DC voltage, resistance), single press the "SEL" button.
• The meter automatically selects the appropriate range for most measurements.
• To power off, long press the "SEL" button again. The meter also features automatic shutdown after a period of inactivity.

4.2 Specific Measurement Modes

4.2.1 AC/DC Current Measurement (Clamp)

1. Select the AC or DC current measurement mode using the "SEL" button.
2. Press the trigger to open the clamp jaws.
3. Enclose only one conductor within the clamp jaws. Ensure the jaws are fully closed.
4. Read the current value on the display.

4.2.2 AC/DC Voltage Measurement

1. Connect the test leads as described in Section 3.2.
2. Select the AC or DC voltage measurement mode.
3. Touch the test probes to the points where voltage is to be measured (e.g., across a power source or component).
4. Read the voltage value on the display.

4.2.3 Resistance Measurement

1. Ensure the circuit is de-energized and all capacitors are discharged before measurement.
2. Connect the test leads.
3. Select the resistance measurement mode.
4. Touch the test probes across the component or circuit to measure resistance.
5. Read the resistance value on the display.

4.2.4 Non-Contact Voltage (NCV) Detection

• Long press the "REL NCV" key to enter NCV mode.
• Move the NCV sensing area of the meter close to the conductor or outlet.
• If AC voltage is detected, the LED indicator will flash and an audible beep will sound.

5. Specifications

6. Maintenance

• Cleaning: Wipe the meter casing with a damp cloth and mild detergent. Do not use abrasives or solvents.
• Battery Replacement: Replace batteries when the low battery indicator appears on the display. Refer to Section 3.1 for instructions.
• Storage: If the meter is not used for an extended period, remove the batteries to prevent leakage. Store in a cool, dry place away from direct sunlight.
• Calibration: For professional use, periodic calibration by a qualified technician is recommended to maintain accuracy.
