Scale  Factor  adjustment

After you have calibrated your meter, you can use the SCALE feature to make fine adjust-
ments to calibration, without affecting the calibration itself.

Example

1.Changing  units of measure from Ah to Coulombs

If you originally calibrated your display to accumulate in Ampere hours, and you now want to

accumulate in Coulombs, you can do this easily if you set the 

SCALE

 to 3600

Lockout Switch must be OFF

Press 3 seconds
