VELLELMAN Pocket Battery Tester
Use the VTTEST7 battery tester to take an easy read on charging batteries. To operate, set to the battery type you want to measure and voltage with the range switch. Failure to select the correct range may result in and inaccurate read or damage to the battery tester. Align probe tips according to polarity to run test and the analogue display will show if the battery is "good" or if it needs to be replaced/recharged.
When your pocket battery tester is not in use, the needle should lay on the black dot on the far left of the scale. If this is not the case, readjust using the zero-position screw on front panel so that your readings are accurate.
