Question Answer
I am trying to take a measurement,
why do the readings frequently
bounce to zero? Chances are you are trying to read a pulsed waveform. Try
setting the measurement mode to ‘Pulsed’ instead of
‘Continuous’.
How do I measure a bipolar output
when there is only a REM and
Active cable provided? Initial units were only shipped with two active leads, Green and
Yellow. Use the Yellow active cable to connect from the Active
port on the ESU-2400 to one bipolar output on the DUT. Use
the Green cable to connect from Dispersive 1 on the ESU-2400
to the other bipolar output on the DUT.
Starting with Rev G units, a Blue wire was added to the
accessory kit. The Yellow and Blue wires can be used to
measure bipolar outputs.
Why aren’t there more pre -
programmed autosequences
provided with the ESU-2400?
We have been restricted by the ESU manufacturers from
including autosequences with the ESU-2400. However, the
Quickstart guide can help with configuring autosequences.
I just want to use the ESU-2400 to
measure current and don’t need all
of the other features. Is there an
easy way to do this?
Yes, you can use profiles to configure the ESU-2400 to boot to
any screen. Select System Tools from the main screen, then
System Setup. The Startup Screen can then be selected and
saved to a profile.
How do I enter text for the
Autosequence title or instructions
to user? Click in the text box to be edited. To enter text, you will need
an external USB keyboard. You can also enter the text from
your PC using the Remote mode.
What is the tissue test, how is it
used? Some generators have the ability to seal tissue and detect when
the seal is made. These generators use a changing load
impedance to detect the seal. The tissue response test uses a
light bulb as a load to simulate changing tissue impedance. This
mode will monitor the current and report the value right before
the output is turned off.
What is pulsed input mode for?
Isn’t Coag a pulsed waveform?
Pulsed mode is for measuring outputs that have a relatively
long duty cycle such as 20mS off, 500mS on. Typically, the
generator will have a special button to enable the pulsed
output mode.
The RF Measure screen shows mA,
but I need to measure watts. Can
the ESU-2400 measure watts? Yes, press the mA RMS text to select the measurement to be
shown. You can also press the Display Parameters button to
select how many measurements are shown on the screen at a
time.
Why do I have two blue REM
cables? The cable with the center pin is used to enable the dual pad
function (REM) on the DUT. This cable is used for REM test
mode only. For RF Power measurements the ESU-2400 shorts
the two dispersive inputs internally. The blue cable without the
pin is used because it disables the REM function on the DUT.
