Important
If the unit is not to be used for an extended
period, the main batteries should be taken out
to prevent possible damage due to battery fl uid
leakage. After reinserting the batteries, be sure
to set the date and time.
Note
The clock in this unit has an error of about 1 minute
per month. Before measurement, be sure to check
and set the time if required.
An internal rechargeable backup battery serves to
keep clock setting on the unit. The backup battery is
automatically charged by the main batteries, but the
retention period for clock setting depends on charging
time (see page 15). Full charge of the backup battery
requires approximate 24 hours.
