Scale selection procedure for E-FLEX 54cm.
After starting the analyzer, if it detects that the connected clamps are multi-scale, the three LED
indicators on the front panel, L1/sc1, L2/sc2 and L3/sc3 , start flashing. In this way the
instrument shows that the unit is in standby and waiting that the user selects the desired current
scale. The LED flashing will last for 30 seconds. After this, the LED indicators stop
flashing and the equipment takes the scale L2/sc2 as a default, which in case of using E-
FLEX 54cm clamps, corresponds to a full scale of 2000 A.
To select the scale manually, press START/STOP button while LED indicators are flashing. After
the first press, the L1/sc1 LED will start flashing, showing that scale L1/sc1 is in train of being
selected (200 A full scale, in case of E-FLEX clamps). If you press START/STOP again, LED
L2/sc2 will start flashing (2000 A full scale, in case of E-FLEX clamps). Finally, if you press
START/STOP again, LED L3/sc3 will start flashing (20.000 A full scale in case of E-FLEX
clamps). If the user continues pressing START/STOP the unit follows a rotating loop, selecting
sc1 – sc2 – sc3 – sc1 – sc2 – sc3, …etc., until you select the desired scale.
After the selection has been made, let the LED flash during 7 s. If one of the three scales
(sc1, sc2 or sc3) is flashing during 7 seconds and the user does not press any key, the unit
will detect the scale selected by the user and store the configuration in its memory to start
recording the information with the selected scale.
After configuring the desired scale (regardless of whether the unit has been self-configured or
the user has selected the scale manually with the START/STOP button), the unit starts verifying
its correct connection, as explained in detail in point 6.5.3. The unit remains in STOP mode,
until the user presses the START/STOP button to start the recording. From this point, the
START/STOP button recovers its main function of starting and stopping the data recording.
Pressing START/STOP during more than 3 seconds, causes the unit to START or STOP the
recording, always on the same file. The unit will never create duplicate files or files with different
names for each record.
If there is a supply interruption while the CIR-e3 is recording, it will automatically restart when
the supply is restored, keeping the previous configuration, recovering the last clamp scale
configuration (if this scale is possible with the detected clamps) and it will automatically start
recording again, i.e. , there is no need to press the START button again. In such case the CIR-
e3 assumes that it has been an accidental power supply interruption and that the auxiliary
power supply has been restored. The unit always detects single scale clamps after the power
supply is reconnected and it will self-configure itself with the suitable scale and will return to the
recording status automatically.
If the user selects a different clamp or scale to the one that was configured before
the power supply interruption and the system restarts, the unit will delete the old
file with recorded data in the SD memory and will generate a new one, using the
new selected configuration.
If there is a supply interruption while the CIR-e3 is in STOP mode and the device has multi-
scale E-FLEX clamps connected, then, when the supply is restored, the unit will restart in the
scale selection mode. That is, with the three LED blinking and waiting for configuration. If the
user doesn’t modify the clamps scale in 30 seconds, the device will restore the previous
configuration and stays waiting in STOP mode.
