When the desired value is reached, the module is switched off without
pressing the function key any further. The ratio is now set and
protected against power interruptions. Now whenever the module is
switched on, this pre-set value is used for measuring line currents.
The ratio setting in existence when the power is switched off is the
same value that is valid when the power is switched on again, without
pressing the function key.
Measuring Operation
After the module has been switched on, the software version is
displayed for three seconds, after which the module starts scanning,
measuring, and displaying the power line parameter values. It starts
with the parameter that was selected whenever the “n” function was
last invoked. If a parameter was being held on display using the “r”
function when the module was last switched off, the module displays
the present values of that same parameter.
In its normal sequential display mode, the measured parameter values
are displayed in the following sequence:
•
Line-to-line voltages
•
Line-to-neutral voltages
•
Instantaneous phase currents
•
Average phase currents
•
Peak phase currents
Press and hold the function key (“F”) to select one of three functions.
The selected function is indicated by the left-most character of lowest
line, and interpreted as follows:
•
‘n’: Key pressed for 0 to 2 seconds: skips the present parameter,
and displays the next parameter
•
‘r’: Key pressed for 2 to 4 seconds: sequential display of
parameters, on/off
•
‘c’: Key pressed for 4 to 8 seconds: re-sets average and peak
current values
The present parameter can be skipped and any other parameter
displayed by manual stepping, even if the automatic sequencing
mode (‘r’) is active. Similarly the ‘c’ mode can be invoked at any time
to delete the existing average and peak current measurements.
