Remember:
Hazardous voltage can shock, burn or cause death !
The unit should only be operated after carefully reading the user manual which is an
integral part of the instrument.
HIPOTRONICS and its sales partners refuse to accept any responsibility for consequential
or direct damage to persons and/or goods due to none observance of instructions
contained herein or due to incorrect use of the equipment.
Further be aware that Safety is the responsibility of the user!
2.0 General
Safety is the most important aspect when working on or around high voltage electrical equipment.
Personnel whose working responsibilities involve testing and maintenance of the various types of
high voltage equipment must have understood the safety rules written in this document and the
associated safety practices specified by their company and government. Local and state safety
procedures should also be consulted. Company, regional or national regulations must be fulfilled
beyond HIPOTRONICS recommendations.
If the instrument is damaged or it is possible that damage has occurred, for example during
transportation, do not apply any voltage. The instrument may only be used under dry operating
conditions.
Do not open the unit; it contains no user replaceable parts.
People with heart pacemakers should not be in the vicinity of this system during operation.
Safety is the responsibility of the user. Always operate the equipment in accordance with
the instructions, always paying full attention to local safety practices and procedures.
This equipment must be operated only by trained and competent personnel who are aware
of the dangers and hazards involved in testing transformers.

2.1 Essential Safety Recommendations
Before connecting the instrument ensure that the device-to-be tested is completely de-
energized and isolated from both line and load. Every terminal should be checked and
verified before connection of the instrument. Ground connections may be left in place.
Never operate the equipment in an explosive environment or where there are flammable
gases or fumes
The instrument must always be grounded (i.e. a safety earth). It must never be operated in
a non-grounded configuration as this may result in electrical shock to the user or damage to
the instrument.
2.2 Summary
Note: Many accidents that happen around high voltage equipment involve personnel who are not
familiar, or perhaps too familiar, with high voltage equipment. Staying alert and ever watchful
requires constant training and awareness of the inherent hazards. The greatest hazard is the
possibility of getting on a live circuit. To avoid this requires constant vigilance - for oneself and for
one's fellow workers.
In addition to the obvious dangers, personnel should be alert to recognize subtle dangers as well.
Therefore, all terminals of a device under test, unless grounded, should be considered to
be live while the test is in progress.
Remember: Safety, FIRST, LAST, and
ALWAYS !

3.0 Introduction
Each KVM high voltage divider is calibrated to a specific low-arm wireless module to ensure the
highest accuracy and precision of the device. These systems can measure DC and AC
waveforms, up to 1kHz, and transmit measurement data to our mobile KVM-W application. The
remote app is designed to be simple, user friendly, and informative. The user now has the ability
to view any two of the available measurement types at the same time through the application. A
‘Hold’ button is also located near the bottom of the screen on the app, that when pressed, will
retain the instantaneous values of the measurements being displayed. The app also has the
capability to record, save, and share test information. All of these new features will be explained
in further detail in the remainder of the manual.

Connection and Setup
11
5Connection and Setup
5.0 Ground Connections
First, make sure to connect the ground from the device-under-test to both the HV divider and
KVM wireless module. The ground for the HV divider is located at the base, and the KVM wireless
module ground stud is on the side (as indicated on pg 10).
5.1 Device Connections
The wireless module should be placed close to the divider and has an internal magnet to help secure it on
a ferromagnetic surface.
Once the proper ground connections are made, the high voltage portion of the device-under-test should be
connected to the top spinning of the HV divider. The BNC cable should attach to the base of the HV divider
and run to the KVM wireless module.
To recharge the wireless module, plug the USB cable into the USB-C port and the wall adapter into a
mains outlet.
5.2 Connecting KVM-W to Mobile Device
To get the KVM-W app on your mobile device, go to the Apple App Store. Search for KVM-W or
Hipotronics, and download the app.
Upon opening the KVM-W app, if you are not already connected to a KVM-W device through
WiFi, it will prompt you to connect to one.
Click on Settings, and it will redirect to the WiFi settings page where you can see all the available
devices to connect to. Select the desired KVM-W that you wish to connect to.
After a couple of seconds it should establish connection, indicated by a check mark next to the
network name. Then return to the KVM-W app, either by hitting back in the upper left of the
screen, or through normal iOS navigation.

12
Connection and Setup
Once returned to the KVM-W app, it will indicate that it is establishing measurement
communication with the device as seen below.
If this connecting times out the first try, then press Retry. It should connect within a couple of
seconds. If measurement connection is unable to be established, go back to the iPhone Settings
menu and make sure you are still connected to the device’s WiFi. Once connected, it will display
the ID of the device below the right measurement display.
The LED indicator on the KVM-W will be a glowing a solid color when it is connected to a mobile
device through WiFi. If there is no device connected to it, then it will automatically go into sleep
mode, and the LED will blink once every 30 seconds. If you are charging the device while it is not
connected to any mobile device, then the LED will blink every 5 seconds until it is done charging,
in which it will then turn a solid color. If the LED does not blink at all after a minute, then the
batteries are dead and it will need to be recharged.

Operating Modes
6.1 Graph
The app can record test data values for RMS, DC, and Absolute Average. To start recording, press the
Play button located to the bottom left of the graph display. The graph will then begin updating
automatically with incoming data values once per second. There are three selectable measurements to
display on the graph. In the bottom left corner of the screen, the labelled buttons indicate whether the
graph is plotting those values or not. To enable or disable any of those options, just click on the button.
A solid color indicates that the measurement is being plotted, and if the button is mostly transparent,
then it is disabled from the graph. The color of the button also correlates to its respective plotted line
color on the graph.
Once the Play button is pressed, the graph will begin updating, a Pause button will replace where the
Play button just was, and a Reset button will appear under the right corner of the graph display. To stop
recording values, press Pause. This will then replace the Pause button with the Play button. When
ready to resume the test and continue recording values, press Play again. To reset the test and start a
fresh recording of measurement values and graph, press Reset.
