Smart Pen Multi-Purpose Meter

This document provides operating instructions for the Smart Pen Multi-Purpose Meter.

Device Description

The image shows a pen-shaped digital multimeter designed for various measurements. It features a display screen, a sharp probe at the tip for testing, and several control buttons labeled "HOLD/*", "SELECT", "Hz", and a power symbol (represented by a circle with a vertical line). The device is compact and portable.

1. METHOD OF MEASUREMENT

⚠️ Attention! Dangerous voltage levels may be present at the input terminals and not displayed.

1.1. MEASUREMENT OF DC AND AC VOLTAGE (DCV & ACV)

1. Select the "AUTO" mode. Voltage and resistance are recognized automatically.
2. Connect the black test lead to the "COM" terminal.
3. Connect the test probe to the point of measurement and read the value on the display. The polarity of the probe will be displayed with a sign along with the voltage.

Note: Never attempt to measure voltages above 600V! Although the indicator can show this voltage level, there is a risk that the internal circuitry may be damaged.

1.2. MEASUREMENT OF RESISTANCE AND CIRCUIT CONTINUITY TEST

⚠️ Attention! To avoid electric shock or damage to the device during resistance or continuity measurements, ensure that the voltage in the circuit is turned off and all capacitors are discharged.

1. Connect the black test lead to the "COM" terminal.
2. Select the "AUTO" mode. Voltage and resistance are recognized automatically.
3. Touch the test probe to the resistance to be measured and read the value on the display.
4. If the resistance is determined to be less than 500Ω, the circuit continuity test will automatically start, and a beep will sound.

Note:

• a) Polarity of the built-in test probe is "+".
• b) If the tester input is not connected to the circuit, i.e., the circuit is "open", the display will show "1" as an indication of out-of-range.

1.3. MEASUREMENT OF CAPACITANCE

⚠️ Attention! To avoid damaging the device, disconnect the circuit power and discharge high-voltage capacitors before performing measurements.

1. Press the "SELECT" button to choose the capacitance measurement mode.
2. Connect the test probe to both terminals of the capacitor and read the value on the display.

Note: The measured capacitor must be discharged before testing. Never apply voltage to the input terminals '+', otherwise it may cause serious damage.

1.4. MEASUREMENT OF FREQUENCY

1. Press the "Hz" button to select the frequency measurement mode.
2. Connect the black test lead to the "COM" terminal (Note: polarity of the built-in test probe is "+").
3. Connect the test probe to the measurement point and read the frequency value on the display.

1.5. NON-CONTACT INDUCTIVE VOLTAGE TEST (NCV)

1. Press "SELECT" to choose the "NCV" mode.
2. Place the top of the multimeter close to an object with AC voltage.
3. When the sensor in the upper part of the multimeter detects an alternating electric field, a sound signal will be emitted, and the corresponding voltage intensity value will be displayed.

Note: This function is used only to detect the presence of an alternating electric field; it is impossible to determine if the measured circuit is safe. Be cautious of electric shock and take appropriate safety measures.

2. BUTTON FUNCTIONS

• "SELECT": Select modes "Capacitance" (capacitance) or "NCV" (non-contact voltage test) or "AUTO" (automatic).
• "Hz": Select modes "Frequency" (frequency) or "AUTO" (automatic).
• "HOLD/*": Hold value and backlight. Short press: hold and release value. Long press: turn backlight on/off.

3. BATTERY REPLACEMENT

1. Battery replacement should be performed when the test leads are disconnected (not connected to the circuit, not under voltage).
2. Open the battery compartment on the back of the device, replace the used batteries with new ones, and close the battery compartment.
