4. Setup: Battery Installation

The SNAKOL SK-216B requires two 1.5V AAA batteries for operation. Batteries are included with the kit.

Figure 4.1: Battery compartment with AAA batteries installed.

This image illustrates the battery compartment of the SNAKOL SK-216B multimeter, showing two 1.5V AAA batteries correctly inserted. The compartment is typically located on the back or side of the device and secured with a cover. Ensure correct polarity when inserting batteries.

1. Locate the battery compartment cover on the back of the multimeter.
2. Use a screwdriver (if necessary) to open the battery compartment.
3. Insert two 1.5V AAA batteries, ensuring correct polarity (+ and -) as indicated inside the compartment.
4. Securely close the battery compartment cover.
5. The device is now ready for use. Replace batteries when the low battery indicator appears on the display.

5. Operating Instructions

To operate the SNAKOL SK-216B, press the Power/Function Selection Key to turn it on. Use the same key to cycle through different measurement functions.

5.1. AC/DC Voltage Measurement

Figure 5.1: Measuring AC voltage in an electrical panel.

This image shows the SNAKOL SK-216B multimeter in use, measuring AC voltage within an electrical panel. The display clearly shows a reading of "223.1V AC". The positive probe (pen tip) is inserted into a terminal, and the negative probe (black lead) is connected to another point, demonstrating a typical voltage measurement setup. The device is capable of measuring both AC and DC voltages up to 600V.

1. Turn on the multimeter. Select the AC Voltage (V~) or DC Voltage (V-) mode using the Power/Function Selection Key.
2. Connect the positive probe (pen tip) to the positive point of the circuit and the negative probe (black lead) to the negative or common point.
3. Read the voltage value displayed on the AV color screen.
4. The device automatically detects AC or DC voltage in auto-ranging mode.

5.2. Resistance, Diode, Capacitance, and Frequency Measurement

Cycle through the functions using the Power/Function Selection Key until the desired mode (Ω for resistance, ⟷ for diode, F for capacitance, Hz for frequency) is displayed.

• Resistance (Ω): Connect the probes across the component to measure its resistance.
• Diode (⟷): Connect the probes across the diode. The display will show the forward voltage drop.
• Capacitance (F): Connect the probes across the capacitor. Ensure the capacitor is discharged before testing.
• Frequency (Hz): Connect the probes to the signal source to measure its frequency.

5.3. Continuity Test

The continuity test checks for an unbroken path in a circuit. A built-in buzzer sounds if the resistance is less than 50Ω.

1. Select the continuity mode (often indicated by a speaker icon) using the Power/Function Selection Key.
2. Connect the probes to the two points of the circuit you wish to test.
3. If there is continuity (low resistance), the buzzer will sound.

5.4. Non-Contact Voltage (NCV) Detection

Figure 5.2: NCV Non-Contact Sensing in action.

This image demonstrates the NCV (Non-Contact Voltage) sensing capability of the SNAKOL SK-216B multimeter. The device is held near a bundle of electrical wires, and a red indicator light is flashing, accompanied by visual representations of "di di di" sounds, indicating the detection of AC voltage. The closer the meter tip is to the power source, the more urgent the alarm sound and the more analog bars appear on the LCD display, signifying stronger electric field detection.

Figure 5.3: Line Break Detection using NCV mode.

This image illustrates the line break detection feature of the SNAKOL SK-216B multimeter in NCV non-contact voltage detection mode. It shows two segments of a single-stranded wire, one electrified and one not. The multimeter is shown detecting the presence of electrification along the wire, and the absence of a signal beyond a certain point helps identify the location of a break in the line. This is a useful feature for quickly diagnosing cable faults.

1. Press the NCV/LIVE Selection Key to enter NCV mode.
2. Move the tip of the multimeter close to the conductor you suspect has AC voltage.
3. If AC voltage is detected, the red indicator light will flash, and an audible alarm will sound. The frequency of the alarm and the number of analog bars on the display will increase as you get closer to the voltage source.
4. This mode can also be used for line break detection in energized wires.

5.5. Live Wire Detection

This function helps identify live (hot) wires from neutral wires.

1. Press the NCV/LIVE Selection Key to cycle to LIVE mode.
2. Touch the positive probe (pen tip) to the wire you want to test.
3. The display will indicate if the wire is live, often with a specific symbol or reading.

5.6. Data Hold and Flashlight

Figure 5.4: Reflective screen and torch illumination.

This image highlights two key features of the SNAKOL SK-216B multimeter: its reflective screen and built-in torch illumination. The reflective screen provides clear and accurate readings even in low-light conditions, enhancing visibility. The integrated torch light, emanating from the tip of the pen, improves visibility in dark environments, reducing the risk of electrical shock by allowing users to see their measurement points clearly.

• Data Hold: Briefly press the "HOLD" button to freeze the current reading on the display. Press again to release.
• Flashlight: Long press the "HOLD" button to turn the built-in flashlight on or off. This improves visibility in dimly lit work areas.

6. Maintenance

• Cleaning: Wipe the device with a dry, clean cloth. Do not use abrasive cleaners or solvents.
• Battery Replacement: Replace batteries when the low battery indicator appears. Refer to Section 4 for instructions.
• Storage: Store the multimeter in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
• Probe Inspection: Regularly inspect the test probes and leads for any signs of damage, such as cracks or frayed insulation. Replace damaged leads immediately.
