Calibration
PCS2 Calibration
When extreme accuracy is required for calibration, allow the PCS2 to warm up for a minimum of 15 minutes before calibration. The following procedures are used for both circuit 1 and circuit 2. Calibrate each circuit independently.
If the device only has an ON state, either STANDBY or ON can be used in the following steps.
1.Plug the PCS2 into a power source.
2.Connect the device.
3.Turn both POTS all the way counter clockwise. At a maximum, this is 20 full turns. The stop (end) can be detected by a subtle clicking sound and feel.
4.Set the device to the STANDBY power mode and wait
5.Turn the PCS2 STANDBY POT clockwise until the STANDBY LED lights.
6.Slowly turn the POT counterclockwise until the LED goes out. Then, very slowly turn the POT clockwise until the LED lights. The
7.Turn the devices off and wait 2 seconds.
Because of hysteresis (the analog circuit components time for changing states) the
8.If the LED is still on, repeat steps 6 through 8 until the LED is not on when the device is turned off.
9.Perform steps 1 through 8 for the ON circuit level.
10.Repeat steps 1 through 9 for the second PCS2 circuit's STANDBY and ON circuit levels.
