Checking the Battery Voltage
Model 820 Technical Reference Manual
Step 3
The third screen automatically appears:
This screen will remain until the
user inputs other commands.The
flashing uppercase (S) indicates
system initiation and will continue
10-45 seconds.
The third screen appears almost immediately showing the title
information for the current or last reading and is programma-
ble by the operator.
At this point, you can change the parameters and begin taking
actual measurements.
When the system initiation is com-
plete, a stick figure in the upper
right corner of the display will
appear seated indicating the
Model 820 is in STOP mode.
Checking the Battery Voltage
The Model 820 continuously monitors its battery voltage to
ensure accurate measurements. It has a battery life of about
sixteen hours. It will turn off automatically when the voltage
falls below 5.7 volts. Therefore you should verify that the
remaining battery capacity is sufficient before you make an
especially critical or lengthy measurement.
Do not press the
B
key during a
measurement since it will pause
the measurement while pressed.
