■ Remove the old batteries and replace
them with four new batteries (LR6, AA,
1.5V), 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, 1.2V) 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.

Setting the clock, which is used for time-stamping measurements, is done only
the rst time the clamp is used or after it has been without battery power for more
than two minutes.

seconds. Enter the date and time using the ▲, ▼, and ► buttons.
The date and time can also be congured 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.
