Calibration 

The model APS voltmeter is accurate to +/- 5% of the output voltage, as shown on the LCD 

display on the instrument panel. It is recommended that this model follow an annual calibration 

cycle to ensure the instrument is in good working order and that the LCD of the integration 

voltmeter is accurate. 

 

 

Battery Charging 

The Model APS comes with two batteries. The lithium-ion battery should be charged after each 

use. The Model APS will indicate when the battery voltage is low, by a slow blinking of the 

Green Power LED, instead of providing a steady glow. The battery charger has an LED. RED color 

LED indicates the battery is being charged. GREEN color LED indicates that battery is fully 

charged. GREEN color LED also means that the battery is on trickle charge, and can be left in 

this condition. The charger can be used with 110v / 240v AC. It is an auto sensing charger that 

can be used throughout the world. Please consult your manual if you have a battery with a 
serial number prior to 827.
