Victor 91 Non-contact High-voltage Electroscope User Manual

1. Safety Rules and Precautions

Thank you for choosing the Victor 91 Non-contact High Voltage Detector. To ensure safe and effective use, please read and strictly adhere to the following safety rules and precautions.

• Always read this user manual thoroughly before operation.
• Before each use, inspect the instrument for any damage and ensure the battery cover is securely in place. Operating with an exposed battery compartment poses a risk of electric shock.
• The insulating rod must be properly connected to the instrument during use to prevent electric shock.
• This instrument is designed for non-contact measurement. Never directly contact high-voltage lines with the instrument.
• Operators must be strictly trained and aware of the dangers associated with high-voltage lines.
• Pay close attention to all labels and symbols on the instrument panel and body.
• Replace the battery promptly when the low battery indicator signals.
• For long-term storage, remove the battery from the instrument.
• Any disassembly or maintenance of this instrument must be performed by authorized personnel only.
• If the instrument appears dangerous or malfunctions, cease use immediately and seal it for professional handling.

Warning: Failure to strictly observe safety rules can lead to personal injury or equipment damage.

2. Product Overview

The RuoShui Victor 91 is a non-contact high-voltage detector designed for safe and reliable checking of AC high and low voltages. It features sound and light prompts, a self-test function, and compatibility with most insulating rods. Its robust design (IP65 protection, shockproof) makes it suitable for harsh working environments.

This tool is ideal for non-contact detection of live voltage, cable fault detection, locating and detecting live high-voltage cables, tracking field wires, and detecting residual or induced voltage.

3. Setup

3.1. Battery Installation

The Victor 91 requires one 9V (6F22) battery (not included). To install or replace the battery:

1. Ensure the instrument is powered off by turning the Range switch to the "OFF" position.
2. Locate the battery cover (component 3 in Figure 3) on the back of the instrument.
3. Open the battery cover.
4. Insert a new 9V (6F22) battery, paying close attention to the correct polarity. Incorrect polarity can damage the instrument.
5. Close the battery cover securely. The instrument cannot be tested safely if the battery cover is not properly installed.

3.2. Connecting the Insulating Rod

Before use, connect the instrument to a suitable insulating rod. The insulating rod joint is component 1 in Figure 3. Ensure the connection is secure to maintain safety and prevent electric shock.

4. Operating Instructions

4.1. Self-Check

To perform a self-check:

1. Turn the Range switch (component 7 in Figure 3) to the "TEST" position.
2. The instrument will perform a self-check, indicated by the buzzer sounding and the LED indicator lights (components 2 and 8 in Figure 3) flashing. This confirms normal operation.
3. If the low battery indicator (component 6 in Figure 3) lights up during self-check, replace the battery.
4. Turn the Range switch to the "OFF" position to power off the instrument after self-check or use.

4.2. Voltage Detection

To detect voltage:

1. Ensure the instrument is securely connected to an insulating rod.
2. Turn the Range switch (component 7 in Figure 3) to the desired voltage range (e.g., 380V, 6KV, 10KV, etc.).
3. Position the LED side of the instrument close to the object or wire to be tested. The closer the instrument is to the wire, the lower the voltage it can detect.
4. If the instrument emits a sound and light prompt (Figure 4), it indicates the presence of voltage at or above the selected range.
5. The detection method involves holding the instrument at approximately a 90-degree angle to the wire (Figure 5). For 380V, the reminding distance is about 5cm; for other ranges, it's about 20cm.

4.3. Ending a Test

When the test is complete:

1. Tilt the insulating rod along the trend of the wire.
2. First, remove the detector from the vicinity of the wire.
3. Then, remove the insulating rod to avoid any impact between the detector and the ground.
4. Turn the Range switch to the "OFF" position.

5. Maintenance

• Battery Replacement: Replace the 9V (6F22) battery when the low battery indicator signals. Ensure correct polarity during installation.
• Storage: If the instrument will not be used for an extended period, remove the battery to prevent leakage and damage. Store in a dry place within the specified temperature and humidity range (-15°C to +55°C, <90%RH).
• Cleaning: Wipe the instrument with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Professional Service: For any repairs or complex maintenance, contact authorized service personnel.

6. Troubleshooting

• Instrument not powering on or low battery indication: Check if the battery is correctly installed with the right polarity. Replace the 9V (6F22) battery if it is low or depleted.
• No sound/light prompt during voltage detection: Ensure the instrument is set to the correct voltage range. Verify the instrument passed the self-check. Make sure the instrument is close enough to the live wire (approx. 5cm for 380V, 20cm for other ranges).
• Erratic readings or false positives: Ensure the insulating rod is properly connected and the instrument is held correctly (perpendicular to the wire). Avoid strong electromagnetic interference sources.
• Physical damage: If the instrument is physically damaged, especially the casing or insulating rod, do not use it. Contact customer support for repair or replacement.

11. Manufacturer Information

Victor Instruments has dedicated itself to the design and manufacture of measuring instruments for over 30 years. VICTOR has also become a top brand for measuring instruments in China, but RuoShui is the new brand used to replace VICTOR on the international market gradually.

During this transition period, all products sold in the RuoShui official shop are original products and will be supplied under the logo VICTOR or RuoShui (depending on inventory). They come with the same after-sales service and quality assurance policy.
