Page 32: Calibration
Otherwise it might be necessary to send the instrument back to factory for recalibration. Calibration in this manual means adjustment. The DCY-2058 and 2059 Stations are accurately calibrated at factory and will not require periodic recalibration under normal conditions. If, for any reason, a recalibration is required, follow the procedure described below. - Page 33 PRESYS ⏐ Instruments DCY-2058 and DCY-2059 In order to return to normal operation move back through the hierarchical levels until reaching level zero.

- Page 35 PRESYS ⏐ Instruments DCY-2058 and DCY-2059 Output calibration Analog outputs can be calibrated by the Stations themselves. Output 1 can be calibrated by input 1 and output 2 can be calibrated by input 2. The configuration of input hardware should be the same as for the output (0 to 5V, 0 to 10V or 0 to 20mA) since the Stations themselves will be measuring the output signal.
