PARTS Of THE BATT-O-mETER
Hold To Test
1.
button; hold this button down
to run the battery test.
Battery chemistry switch
2.
; a three-position
switch to select battery chemistry type:
Alkaline, Rechargeable (ie. Lithium-ion, NiCd,
NiMH), Carbon Zinc.
External Battery Contacts
3.
; touch the battery
terminals to these contacts to test standalone
batteries making sure polarities match. Batteries
supported: 9 volt, 1.5 volt, and 3 volt.
Power Probe
4.
; gold plated detector, coupled
to a highly sensitive, high impedance circuit.
In order to work properly, the probe must be
free of oil and other contaminants. Insert this
plug into your 9 volt device to test internal
battery or use it to aid in standalone battery
test of 1.5 volt batteries.
How it Works
Stomp boxes and instruments use a standard
stereo1/4” diameter phone plug and jack. These
instruments and devices sense the insertion
of the 1/4” mono plug to turn on the power
(Figure 1.)
The Batt-O-Meter can measure critical
information that lets you know how much longer
the battery will work without making direct
contact to the positive contact of the battery
usually required.

attempting to run the Self-Test, the test will fail and
the LED screen will flash “pL6” prompting you to
