The calibration signal source (hereinafter referred to as the calibrator) is the multifunctional microprocessor-controlled unit used to reproduce high-precision DC voltage and current values for calibration, checkout and adjustment of ordinary measuring instruments under laboratory and industrial conditions.
Manufactured in accordance with the technical conditions EI.120.00.000 TC
| Использование | Etc |
The calibrator is the programmable voltage (-10...+100 mV, −1...+10 V) and current (0...5 mА, 0...20 mА, 4...20 mА) source. As for the number of reproducing channels, the calibrator is single-channel. The calibrator consists of the built-in stabilized DC power source (the voltage output is 24 V) with the overload and short circuit protection device and galvanically separated from other circuits. The additional standard loading resistor for 100 ohm ±0,01 % may be optionally included into the calibrator. The resistor is connected to the terminals independent from circuits and located at the rear plate of the calibrator.
Analog output signals of the calibrator are controlled using external digital voltmeters connected to relevant terminals.
Voltage and current values are entered into and stored in the memory from the push-button keyboard located at the calibrator’s body frame. The output voltage and current value in each range is stored and extracted from 94 points divided into 8 tables with 8 points each.
