Digital Circuit Board functions as a Voltmeter, Ammeter, Amp Hour Accumulator, and Timer. Great for project units as well. Wires Between Output circuit breaker and Negative clamp cable. Terminal 13 (1/4" Spade) wires to the output or back plate of the rectifier. Used on positive rectifier output systems.
Display and AccuracyVoltage• Open circuit voltage between 12.0–13.0 is displayed to 0.1 V and is accurate to +/- 0.1 V at DC levels.
• Open circuit voltage below 12.0 or above 13.0 is displayed to 0.1 V and is accurate to +/- 2%.
• Charging voltage is displayed to 0.1 V and is accurate to +/- 2%.
Current• Below 10 A, current is displayed to 0.1 A and is accurate to +/- 0.3 A.
• At 10 A or above, current is displayed to 0.1 A and is accurate to +/- 5%
Amp Hours• Amp Hours are measured in whole units and represent the charge sent to the battery
NOTE: This is NOT a measurement of actual battery amp hours, but a running display of how many amp hours the battery is currently accumulating.Charge Time• In Battery Test Mode, the timer displays a countdown timer from 15 minutes to zero.
• In Battery Charge Mode, the timer displays a total elapsed time.
