ALSTOM MVAJ27L1FB0784D Pulse input module

Program the supply to full-scale voltage. When the output voltage is at full-scale ± 0.1 %, send the command : "TRVG". This will store the voltage read gain value in the EEPROM for later use in readback calculations. Send command "MV" to initiate a read of the voltage channel. Check to make sure the reading is now correct (voltage should equal full scale). Program and measure the voltage for several points throughout the supply's range. The programming and readback should track closely.

CURRENT CHANNEL CALIBRATION: 

Turn circuit breaker to OFF position. Either connect the load to the power supply and adjust it such that the supply will be able to put out its full current or connect the shorting strap to the power supply. If using an external shunt connect the shunt in series with the load or shorting strap. Turn circuit breaker to ON position. Send command "SR".
