■
Unclamp and remove the
instrument from any connections
and turn the rotary switch to the
OFF position.
■
Use a Phillips head screwdriver
to unscrew the two attachment
screws and remove the battery
compartment cover.
■
Remove the old batteries and
replace them with four new
batteries (LR6, AA, 1.5 V),
observing the polarities.
■
Close the battery compartment
cover and tighten the two screws.
■
Check for the proper operation of
the device.
NOTE:
The alkaline batteries can be replaced by NiCd or NiMh
rechargeable batteries (AA, 1.2 V) having similar characteristics.
However, the time between the low battery message and the Auto Power
OFF will be shorter with the rechargeable batteries.
Used batteries must not be treated as ordinary household waste. Recycle
them appropriately.
5.2 SETTING THE DATE AND TIME
Setting the clock, which is used for time-stamping measurements, is done only
the first time the clamp is used or after it has been without battery power for more
than two minutes.
Set the function switch to Ω+A. All icons on the display light for approximately two
seconds. Enter the date and time using the ▲, ▼, and ► buttons.
The date and time can also be configured before a measurement in SET-UP
(see
§ 4.4, menu #7 & #8).
NOTE:
If time-stamping is not needed, this operation can be skipped by
pressing the ► button until the measurement screen corresponding to
the switch setting (Ω+A, A, MR or SET-UP) is displayed.
