Description
Overview
GAOTek high precision multifunction process calibrator supports voltage, current, resistance, frequency, pulse, and switch value measurement and output, with active and passive current options. A 3.5 in (89 mm) TFT LCD screen provides a simultaneous display of measurement and output data, offering flexibility with manual and automatic step functions. The unit has a 5000 mAh lithium battery, an automatic power-off function, and supports on-site use with a DC 24 V loop power supply.
Features

- Active and passive current output support
- Thermal resistance and thermocouple simulation in temperature form
- Two-wire transmitter simulation
- Resistance measurement options
- High accuracy of 0.01%
- Two mutually isolated channels for synchronous measurement and output
- Functions include manual step, automatic step, and a combination of both
