Transient Current Thresholds - AEMC PowerPad 8436 User Manual

■
4V or 3U: all channels have the same threshold.
• Press the  button, then use the ,  buttons to highlight the value of the threshold in yellow.
• Press the  button, then use the , ,  and  buttons to change the threshold. The unit can be the V or the kV.
■
3V + VN: all channels have the same ratio and the neutral has a different ratio. Proceed as when there is only one ratio, but
perform the operation twice.
■
V1+V2+V3+VN or U1+U2+U3: each channel has a different ratio, to be configured. Proceed as when there is only one ratio,
but perform the operation several times.
Validate with the  button. To return to the Configuration menu, press
NOTE: Transient thresholds cannot be changed if the instrument is actively searching for transients.

4.8.2. TRANSIENT CURRENT THRESHOLDS

Pressing the A function button in the Voltage Threshold menu (Figure 4-16) displays the Current Thresholds menu. This configures
the current thresholds (independently of the current sensors detected by the instrument). Configured thresholds can be the same for
all channels or different for some or all of them.
To change the current thresholds, press  .
Use the arrow buttons (, ) to choose the configuration of the thresholds.
■
4A: all current sensors have the same threshold.
Press the  button, then use the ,  buttons to highlight the value of the threshold in yellow.
•
• Press the  button, then use the , ,  and  buttons to change the threshold. The unit can be the A, the kA or the mA.
■
3A + AN: all current sensors have the same threshold and the one connected to the neutral has a different threshold.
as when there is only one ratio, but perform the operation twice.
■
A1+A2+A3+AN: each current sensor has a different threshold, to be configured. Proceed as when there is only one ratio, but
perform the operation several times.
Validate with the  button. To return to the Configuration menu, press
NOTE: Changing the thresholds in the transient mode is impossible if the instrument is searching for transients.
