 U1+U2+U3 or V1+V2+V3: each channel has a different ratio, to be programmed.
Proceed as when there is only one ratio, but perform the operation several times.
Validate with the

key. To return to the Configuration menu, press .
Note: the primary and secondary voltages can each be configured with a multiplier factor of 1/√3.
4.8. TRANSIENT MODE (FOR THE C.A 8333 ONLY)
The mode is used to configure the voltage thresholds and the current thresholds of the transient mode.
4.8.1. VOLTAGE THRESHOLDS OF THE TRANSIENT MODE
A first screen, displayed by pressing the V icon (or U, for set-ups without a neutral), is used to configure the voltage thresh-
olds.
The thresholds programmed can be the same for all channels or different for some or all of them.
Figure 29: The Current thresholds screen in the Transient Mode menu
To change the voltage thresholds, press

.
Use the arrow keys (,) to choose configuration of the thresholds.
 3V or 3U: all channels have the same threshold.
 Press the

key, then use the , keys to highlight the value of the threshold in yellow.
 Press the

key, then use the ,, and  keys to change the threshold. The unit can be the V or the kV.
 V1+V2+V3 or U1+U2+U3: each channel has a different ratio, to be programmed.
Proceed as when there is only one ratio, but perform the operation several times.
Validate with the

key. To return to the Configuration menu, press .
Note: Changing the thresholds in the transient mode is impossible if the device is searching for transients.
4.8.2. CURRENT THRESHOLDS OF THE TRANSIENT MODE
A second screen, displayed by pressing the A icon, is used to configure the current thresholds (independently of the current
sensors detected by the device).
The thresholds programmed can be the same for all channels or different for some or all of them.
