8.1.4. How to set the Clamp Type
The value of this parameter must be always equal to the clamp type you are using.
Two types of clamps are available:
STD: for Standard clamps or Current Transformer
FLEX: for Flexible clamps.
Set the desired value by pressing the multifunction keys F3 and F4.
8.1.5. How to set the value of the transformer voltage ratio (TV RATIO)
The instrument can also be interfaced with step-down transformers in the equipment under
test: it can display the value of he voltages present on the primary winding of these
transformers. To do this it will be necessary to set the value of the transformers’ windings
ratio from 2:1 to 3000:1. The default is set at 1:1 for measurements of none transformer
systems.
Select “TV RATIO” in the ANALYZER CONFIG menu. Set the desired value by pressing
the multifunction keys F3 and F4.
8.1.6. How to enable/disable the password
The instrument is provided with a protective routine to avoid the risk of being disturbed or
interrupted during a recording or an energy measurement. Once a recording or a direct
energy measurement has been started (with the option “PASSWORD” enabled), after
about 3 minutes from the last key pressure or switch rotation it won’t be possible to press
START/STOP to stop the recording, “PASSWORD” will be displayed and it will be
necessary to insert the password.
In order to insert the password (which is not changeable), press the multifunction keys in
the following sequence (within 10 seconds):
F1, F4, F3, F2
