Features

Electrical Parameters Output: Voltage is up to 1100 V, current is up to 30 A at a frequency 10 Hz ~ 500 kHz.
Resistance Simulation: Continuously variable range, 1 Ω ~ 1100 MΩ, pulse output range: 1 Hz ~ 2 MHz.
The output current has high stability (the typical value is better than 10 ppm/h) and high accuracy (the typical value is 50 ppm/a), and its measurement accuracy is higher than the international similar products.
Value Adjustment Method: Fixed-point, rotary encoder, step and potentiometer (option).
Output Switch: The output can be turned on/off arbitrarily by one-touch operation.
TC and RTD simulation: Support for simulation of up to 8 types of TC and 6 types of RTD.
Strong load capacity of AC, can drive various types of analogue meters and digital meters, so the applicable range of measured instruments is very wide.
The protection of voltage and current sources ensures high reliability under complex conditions.
Excellent Human-Computer Interaction: Large LCD touch screen display, touch and button operation modes, easy for users to measure manually.
Transmitter Measurement (Option): Measure the secondary DC signal of the transmitters.
Proprietary Software (Option): Support the calibration of the checked meters by semi-automatic or full-automatic, data management and report export.
