SETUP MODE
Setting the Clock
This meter includes a clock that records the date and time
along with measured data.
1. Press and hold CLOCK for longer than 2 seconds.
2. Press or to adjust the number, press CLOCK to
adjust the next item.
3. The setting adjustment order is year→ month→ day→
hour→ minute→ second. Press CLOCK to complete
adjustment. To cancel a setup process, press POWER.
Note…
An internal (rechargeable) backup battery runs the clock
when the meter is turned off. The backup battery is
recharged by the main batteries. The clock will run for 30
minutes on the backup battery alone. If the meter will not
be in use for an extended period (one month or longer),
remove the main batteries to prevent possible damage due
to battery fluid leakage. After reinstalling the batteries, set
the date and time.
