According to the type of alarm selected, crossing of the alarm threshold will be
indicated by the appearance of or and a continuous beep at high or low fre-
quency.
Press the
AL
button again to exit the alarm function (the
AL
symbol disappears).
If the instrument is switched OFF, without the alarm mode being exited, this
configuration will be saved. The instrument will thus automatically switch the alarm
function ON again when the instrument is next switched ON.
Setting the alarm threshold
To programme the alarm threshold for resistance measurement it is necessary to first
press the
ON + AL
sequence.
The
AL
symbol is displayed and the last digit of the threshold value flashes, as a
reminder that you are in threshold reset mode. This value is changed by pressing the
Ω
Ω
Ω
Ω
Ω
button (increase) or
A
button (decrease). This new threshold value will be kept until
it is again changed, even after the clamp has been switched OFF.
The high alarm threshold can be between 1 and 199
Ω
. It is programmed in at the
factory before delivery of the clamp.
OFF
(instrument switched off) exits alarm threshold programming mode.
MEMORY
(
C.A 6415 exclusively
)
Zero reset of memory
Press the
ON + MEM
sequence for 3 seconds to display
, this starts the clear
memoory procedure. At the 5th beep, the memory is cleared. Return to resistance
measurement is then automatic.
Recording a measurement
The recording of a measurement is only possible if the memory is switched on with the
ON + A
sequence (
MEM
symbol displayed).
Press
MEM
to record the displayed value. The number of values in memory goes up
by 1 and a long beep confirms the recording.
If the
symbol or the
symbol is continuously displayed, recording is
impossible because the clamp is not correctly closed or the battery is too low.
When the 99th value is recorded, the
MEM
symbol flashes to tell the user that the
memory is full. It is then no longer possible to record new values. If
MEM
is pressed
again there is no effect other than that a beep is emitted to indicate that recording is
prohibited. The memory should be reset to zero (after being re-read if necessary).
