Type the new scale factor (e.g. 0.1)
Press OK
5. Press „MENU‟ to return to the measurement display.
The PM1000+ is now ready to make measurements using a current transducer with a
voltage output.
3.5. TO CONNECT A VOLTAGE TRANSFORMER / TRANSDUCER
The PM1000+ may be used with a voltage transformer (VT) or other transducer to
extend its measuring range. Follow the manufacturer‟s instructions for the safe use and
installation of the transducer.
The output of the transducer is connected to the normal VHI and VLO terminals.
Normally the positive or HI output of the transducer will be marked with the point of an
arrow or a „+‟ symbol. Connect this terminal to the VHI input of the PM1000+.
Voltage Scaling.
A voltage transformer (VT) produces a voltage output which is proportional to the
voltage being measured.
To measure the correct voltage on the PM1000+, use the scale function of the analyzer
to scale, or multiply, the VT output current.
For example, when measuring with a 1000:1 VT a scale factor of 1000 must be used.
Press ‟MENU‟
Select „Inputs‟ and press
Select „Scaling‟ and press
Select „Volts‟ and press
Use the delete key to clear the entry.
Type the new scale factor (100)
Press OK
Press „MENU‟ to return to the measurement display.
The PM1000+ is now ready to make measurements using a VT.
