4.1 INSERTING THE BATTERIES
Refer to §11.2.
4.2 COMMISSIONING THE DEVICE
With the clamp closed and not clamping any conductor, set the function switch to a
position other than
OFF
. All icons of the display unit light for approximately 2 seconds,
before possible entry of the date and time (see next section).
During the first few seconds of operation, the clamp automatically adjusts correction
factors serving to optimize the impedance measurement. This correction makes it
possible to allow for the variations of the measurement head air gap that may occur in
some particular conditions of temperature and humidity.
During this adjustment, the screen displays
CAL GAP
. If the clamp detects a problem,
it indicates
Err CAL
when the switch is set to
Ω+A
. It is then necessary to check the
cleanliness of the air gap, check that no conductor is encircled, and switch off and
back on.
When this adjustment is done, the clamp displays the screen corresponding to the
switch setting.
Note: the switching off of the device is described in chapter 9.
4.3 SETTING THE INTERNAL CLOCK
Setting the clock, which allows time-stamping of the measurements with a view to their
storage, is done only the first time the device is used or after the device has been
without battery power for more than 2 minutes.
Note: if time-stamping is not necessary, because for example a user has no need of time-
stamped measurement records, this operation can be skipped. To skip setting the date and time,
press the
► key until the measurement screen corresponding to the switch setting
(
Ω+A
,
A
,
MR
or
SET-UP
) is displayed. The date and time can be set later in the
SET-UP
position and
the Hour and Date screens; see chapter
, menus 7 and 8.
Set the date and time. The year, month, date, display mode (AM/PM - display from
01:00 to 12:00, symbol A. or
P.
or 24-hour, symbol
24H
), and time. Modify the
blinking value with
▲ or ▼ and validate by ►. At the end of the procedure, the
display unit displays the screen associated with the function selected
(
Ω+A
,
A
,
M
R
or
SET-UP
).
The operator must change between standard and daylight saving time manually.
