Quick Charge C1600 - Manual (Page 3)

TROUBLE SHOOTING:
Voltmeter does not work, or reads low.
Sense lead to clamps broken. Weak corroded clamps, or dirty battery post’s can cause a
resistance and make the meter read low. Clean clamp jaws, and post’s with a wire brush.
Solenoid drops out prematurely, or cannot pack a load.
Check clamp condition, weak clamps will not hold, or defective solenoid.
Times out too soon.
Check timer setting.
Digital voltmeter accuracy
On 12 volt batteries the meter is accurate to ± .05 volts. To check accuracy, first clean the load
clamp jaws with a wire brush, then connect to battery. Connect the leads of a secondary digital
voltmeter with minimum accuracy of ± .01 volts to the jaws of the clamps. As an example, if the
load tester meter reads 12.00, the secondary volt meter should read between11.94 - 12.06. If the
reading falls outside this range, the load tester meter should be re-calibrated or replaced. Contact
Quick Charge for illustrative instructions on re-calibrating and replacing meter.
The meter requires 5 volts to operate accurately. A load test on a 6 volt battery where the voltage
falls below 5 volts will cause the meter to register inaccurately.
Analog ammeter accuracy
Keep the needle zeroed on meter.
