Clamp Multimeter Unit UT208B — AC/DC current 1000A, AC/DC voltage 1000V, 60MΩ, 60mF, analog scale, LPF, LoZ

Unit UT208B is a clamp-style multimeter designed for field use and electrical diagnostics. It measures AC and DC current up to 1000 A and AC/DC voltage up to 1000 V. The instrument includes a high input resistance of 60 MΩ, capacitance measurement to 60 mF, an analog-style scale for quick visual interpretation, a low-pass filter (LPF) for stable readings on variable signals, and a low-impedance (LoZ) mode to prevent ghost voltages. The compact clamp design enables non-contact current measurement while maintaining portability for maintenance and troubleshooting tasks.

Advantages

The clamp multimeter provides wide measurement ranges that cover heavy-current and high-voltage tasks without the need for external clamps or adapters. High input resistance supports accurate voltage measurement with minimal circuit loading, while the LPF stabilizes readings on noisy or fluctuating waveforms. The LoZ function reduces false readings caused by induced or stray voltages. An analog-style scale gives an intuitive overview of changing values, useful during dynamic tests or when tracking trends in real time.

Suitable for

• Electrical installation and maintenance in residential, commercial and light industrial sites
• Troubleshooting of motors, generators and power distribution circuits
• Field service and on-site diagnostics for HVAC and refrigeration systems
• Verification of battery and capacitor circuits where high-capacitance measurement is required

How to use

Before use, visually inspect the instrument and clamp jaws for damage and ensure test leads (if used) are in good condition. Select the appropriate measurement function and range for the parameter to be measured. For current measurements, open the clamp jaws and place them around a single conductor only; avoid clamping around multiple conductors. For voltage and capacitance measurements, connect test leads as required and observe polarity when measuring DC. Use the LPF mode when measuring noisy or variable signals to obtain a more stable reading, and enable LoZ mode when there is a risk of reading phantom voltages. Follow standard safety practices for working on live circuits, including appropriate personal protective equipment and isolation procedures when necessary.

Usage recommendations

Use the LPF option when measuring variable-frequency drives or heavily distorted waveforms, and switch to LoZ mode when verifying voltage presence on disconnected or lightly loaded circuits to avoid false indications. Regularly check the clamp and insulation condition, and calibrate or verify accuracy periodically if used for critical measurements.
