VERY IMPORTANT:
After the SD card insertion wait 12 seconds before starting data recording. After
completing the recording and stopping the data recording process with the
START/STOP button, the user must wait 5 seconds before removing the
memory card.
The unit only detects cards with the FAT 16 format. If you use an SD memory
card with a FAT 32 format, the unit will not be able to write on the card and it will
display the error flashing the REC LED.
Please do not use cards which already have data records that you wish to store
and make backup copies of the stored information frequently.
6.5 Start-up sequence
The analyzer does not have a screen showing the parameters being measured, so that you can
not check whether the connection is correct. Therefore, we recommend to sequentially follow
the process explained below. Follow the steps sequentially and be aware and read the error
messages displayed by the analyzer LED indicators.
Follow the steps 1 to 9 explained in detail below.
1. Insert SD card.
2. Insert A connector of current clamps.
3. Insert B connector, voltage references.
4. Power the analyzer.
5. Select the scale of the current clamps (in flexible clamps).
6. Check the voltage phase inversion.
7. Install the current clamps.
8. Check the installation of the current clamps.
9. Start the recording process.
After inserting the SD card in the analyzer's slot, connect the instrument and start measuring the
electrical parameters. The connection process is explained in detail in the following points.
6.5.1 Powering and connecting the unit
Insert connectors “A” and “B”, corresponding to the current and voltage sensors of the CIR-e³
analyzer, respectively, before connecting the unit to the supply. The analyzer is powered
through the brown and green auxiliary power supply wires. After connecting the auxiliary power
supply cables, the unit will automatically detect the current clamps.
If the analyzer identifies that the current clamps are a single scale type, it will detect them
automatically and it will self-configure the current scale (current ratio) and will store it in its
internal memory. This scale will be used to perform the calculations required to obtain all other
electrical parameters stored in the memory. In case of single scale, CIR-e³ will start the boot
sequence. It will perform a sequential ignition of LED indicators L1, L2, L3 and POWER LED.
After boot process, the LED REC lights and the instrument starts the verification of possible
connection errors in the voltage probes. This process is explained in detail in section 6.5.3 of
this manual.
If the analyzer identifies that the current clamps plugged to connector A, are a multi-scale
type, the analyzer then moves onto the next step, which is the selection of the scale of the
current clamp (choice between the available scales of current clamps connected in connector
A). The three LED indicators L1/sc1, L2/sc2 and L3/sc3 will start flashing, so that you can select
