Smart LT Manual Dynatronix, Inc. 10. Calibration Procedure All calibration procedures must be performed by a qualified service technician. Review the entire procedure before starting. LT1200X Series CALIBRATION 10.1. Overview All calibration steps are performed using the LT front panel interface. The calibration values are written to non-volatile memory where they are retained permanently. The number of calibration steps required depends on the configuration of the unit.
PAGE 58
Loads The load should be a resistor or set of resistors of approximately twice the required wattage to prevent injury to personnel or equipment and to prevent significant temperature drift. The resistor size is calculated so both the current and voltage can be calibrated with the same load. This can be done because the calibration for the high end values takes place at 95% of rating. An adjustable carbon pile load works well. EXAMPLE LOAD CALCULATION: Power supply rating is 12-100 or 12 Volts at 100 Amps.
PAGE 59
Smart LT Manual Dynatronix, Inc. Voltage Calibration Load: The current developed across the load should be 50 amps at 12 volts. To determine the resistor value use Ohms law: 12 Volts / 50 Amps = 0.24 ohms To determine the wattage use: 12 volts x 50 amps = 600 watts To calibrate the voltage settings it will be necessary to connect a load resistor with a value of 0.24 ohms and 1200 watts (twice calculated wattage). 10.1.2.
