Control panel description:
1. Play: Starts the measurement, start the car subsequently.
2. Maximum battery voltage before starting the car.
3. Minimum battery voltage peak reached during ignition.
4. Close: Closes the Battery Scope measurement window.
Remark: when the Battery Scope instrument is used, power the bit Tune using the mains adapter. While performing
the measurement, connect the alligator supplied in the packaging between the car chassis and the
BNC PROBE LEFT connector.
Refer to
section 7.9 with measurement examples.
6. BATTERY SCOPE
This tool implements a VDC oscilloscope,
which monitors the behavior of the vehicle’s
battery voltage during engine start or during
the audio system operation.
The active inputs for this type of
measurement are:
SPK Left+ SPK Left -
1
4
2
3
Purpose of the measurement:
In audio installations some malfunction or unwanted noise on the speakers may occur, especially when starting the
engine.
When starting the engine, the vehicle’s battery voltage may drop, for a few moments, below 8 Volts. This can
compromise the normal operation of some audio device.
The Battery Scope allows to measure, by displaying it, this phenomenon, which otherwise is not detectable by an
ordinary tester, given the brevity of the duration. Once you have found that the problem is caused by low battery
voltage, proceed to battery recharging or replacement.
