Chapter 1 Overview
1.1 Introduction
This signal calibrator can measure and output various signals,
including voltage, current, thermocouple, resistance, and
thermal resistance signals. An HD LCD and silicone button with
distinct functions are used, providing clear display and easy
operation. The calibrator has a long standby time, a high
precision level and programmable output. It is widely used for
commissioning for laboratories, industrial site PLC and process
instruments and electric valves.
1.2 Functions
Voltage signal: output and measurement of 0-30 V,
0-24 mV, and 0-100 mV
(Maximum output is 15 V)
Current signal: output and measurement of active
and passive 0-24 mA and 4-20 mA
Thermocouple: output and measurement of K, E, J, T,
R, B, S and N
Resistance/thermal resistance: output and
measurement of 0-400 Ω and -199°C-650°C (the
minimum resistance output is 15Ω)
* Note: Resistance/thermal resistance is only for SUP-C703S
