Zero adjustment
For accurate ohmic measurements, it is recommended that a zero adjust is performed when changing probes.
To perform a zero adjust, use the included zero bar.
When performing a zero adjustment, place the source pin on the outer copper surface of the zero bar and place the
sensor pin in one of the holes of the zero adjust bar.

Connections and controls

Zero adjustment procedure
Select “0-ADJ”.
The BITE5 will prompt you to make a zero adjustment bar.
Select YES.
NOTE: Place the probes on the zero adjustment bar as shown within 10 seconds of selecting YES, or the BITE5 will time
out.
This zero adjustment will begin. Hold probes on zero bar until adjustment is complete.
Operation

Configuration of string

Performing an impedance test
In the ohm mode, the BITE5 will record and save voltages, impedance values and temperature. These measurements
can be performed on individual cells or sequentially on battery strings. These measurements can be taken on any
individual battery up to 200 V DC.
Operation:
Measuring and saving individual battery measurements.
Connect the impedance leads to the input connector of the BITE5.
On the BITE5 select “Ω”.
Select “Meter”.

Performing an impedance test

Select “Limit” if you would like to program impedance and voltage limits for the measurement.
This screen will allow you to program a warning and alarm limit for the impedance value and a lower limit for the
voltage. This is an optional step. Select OK when done.
Note this feature can be disabled as well by selecting OFF.
Start testing by place the probes across the battery.
The BITE5 will beep when the measurement is complete.

Start testing by placing the probes on the first cell in the string.
The BITE5 will beep when the measurement is complete and save the cell voltage, cell impedance, and cell temperature
to memory automatically.
The results will be displayed on the screen.
Move to the next battery in the string and take a measurement.
The recorded values will be displayed on the screen.
Continue taking a measurement of each cell in sequence on the string until you reach the last cell in the string.
