PTE-100-C PRO

2. Connect the receptor’s input between the common (“0”) and the
current output tap that best accommodates the needed test range.
Always use the appropriate current range tap. This will keep distortion to a
minimum and will make regulation easier.
3. Use the button to identify the used tap to the instrument.
The PTE-100-C PRO does not detect the
current tap you are using,
unless you ‘flag’ it using the TAP button. Some measurement and
protective functions will not work if the green LED under the used tap
is not lit.
4. Disconnect any unneeded cables from the unit.
5. Press briefly and release to ensure that current taps, rather
than voltage taps, are selected for display. The “A” indicator should
lit at the right edge of Display #2.
6. Press the button to switch the output on. Its red LED will lit
and some non-zero reading will be shown in Display #2, unless
you have left the output circuit open.
Display #2 needs about 2 seconds to stabilize itself. The decimal point will be
automatically placed to the biggest accuracy possible for the selected output.
All the power current and voltage outputs are energized when you
switch the injection ON, even though Display #2 shows ZERO.
Likewise, the voltage present in each tap depends directly on the
knob’s position. You cannot regulate each tap independently.
Regulate the injected current turning the variac knob gently while you ob-
serve Display #2.
If you want to use percentage regulation, set a nominal value in Display #1
using the “%” function and activate the percentage mode pressing .
If you want to know the voltage present at the selected current tap, activate
the
Vtap function to have it shown on Display #1.
