5.1 Calibration
The SDTA-01 does not need a periodic maintenance, however if the output values
provided by the SDTA-01 are erratic (after verification), the MULTITEL power
monitoring system’s may be programmed to compensate the differential in
measurement.
Tools and/or equipment required for calibration:
•
AC voltage clamp-on RMS multimeter
•
Terminal or portable computer to communicate with MULTITEL power
monitoring system (Emulation of VT-100, ANSI in some case)
