Handheld signal calibrator with LCD display and keypad

WUQ

WUQ 4-20mA 0-10V mV Signal Generator Calibrator Tester

SKU CH-MCCB-70CJN

Generates 4-20mA, 0-10V and mV signals for calibration with built-in fuse protection against 110V or 220V misconnection

  • TypeTest Instrument & Gauge Parts
  • Built-in fuse protects against 110V or 220V supply errors
  • High-stability reference chips maintain calibration accuracy over temperature and time
  • Dedicated keys for every function give immediate, error-free operation
  • Internal battery with low power draw provides extended standby time

Signal generator with 110/220 V fuse

This WUQ calibrator produces 4-20 mA current, 0-10 V voltage and millivolt signals for testing industrial control loops. It suits technicians who need a portable source to verify transmitters, actuators or PLC inputs during commissioning or maintenance. The built-in battery gives long standby time and fast key response with zero delay. Buyers who require higher current ranges or additional waveform types should look elsewhere.

Easy bench setup with protected inputs

A built-in one-time quick-break fuse protects the instrument if 110 V or 220 V supply is accidentally connected to the signal terminals. High-stability reference and amplifier chips maintain accuracy over temperature and ageing. Independent keys for each function make operation straightforward without menu navigation. Users needing automated logging or computer control will find this unit lacks those interfaces.

Questions about this item

How can I verify the calibrator is working correctly after powering it on?

The built-in one-time quick-break fuse protects against damage if 110V or 220V supply is misconnected, and stable DA, reference voltage, and operational amplifier chips maintain temperature stability for reliable long-term readings.

What comes in the box and what must I purchase separately?

The unit includes a built-in battery for low power dissipation and long stand-by time with fast, zero-delay key response; no external power supply or additional accessories are mentioned in the specifications.
