APSL-C216/C256 Multifunction Process Calibrator

Product Overview

The APSL-C216, APSL-C256 and APSL-C226 Multifunction Process Calibrators are high-accuracy handheld signal measurement/output instruments. They can simultaneously measure and output various industrial process signals including voltage, current, resistance, frequency, thermocouples and RTDs. When equipped with an external high-accuracy intelligent pressure module, they can calibrate pressure transmitters on site.

They can replace measuring and calibration instruments such as current sources, voltage sources, resistance boxes, electronic potentiometers and frequency meters.

They are mainly applied for on-site industrial signal calibration and fault diagnosis, and also suitable for signal measurement and calibration in chemical industry, military industry, various research institutes and laboratories.

Highlights: powerful protection—IP67 waterproof rating with automatic protection against accidental 220 V on any signal terminal; measure/output of voltage, current, frequency and resistance, with current output supporting both active and passive modes; simulation of RTDs and thermocouples as temperature; two-wire transmitter simulation; two mutually isolated channels supporting simultaneous measurement and output; manual step, automatic step, 0–100% step and ramp output; white LED backlight with manual adjustment and auto power-off for field use; a DC 24 V loop supply for on-site commissioning; unique automatic recognition of 3-wire and 4-wire connections; standard AAA batteries for easy replacement; automatic and manual cold-junction compensation for thermocouple measurement and output; an optional APSL high-accuracy intelligent pressure module for pressure measurement; and the ability to add new thermocouple and RTD types on request.
