User instructions and information
Connecting accessories
Connect the instrument, cables, electrodes and, if necessary, grounding according
to the measurement method to be used.
Measurement methods
Point-to-point measurement (Rp-p)
Connect the BNC plug ends of the wires to the
instrument and the black shielding wire connectors
to the black sockets of the electrodes and the red
measuring wire connectors to the red sockets of the
electrodes.
Measurement of resistance to ground (Rg)
Connect the BNC plug ends of the wires to the
device and the connector of one of the black
shielding wires to the black socket of one of
the electrodes. To the red socket of the same
electrode, connect the red wire connected to
the black shielding wire already in use. Connect
the other red measuring wire to the ground.
The use of the other black shielding wire is not
necessary for this measurement method.
Surface resistance measurement (Rs)
Connect the BNC plug ends of the wires to the device and the
two red measuring wires to a ring electrode. (Ring electrode is
not provided in the AIJGO-61 product package.) The use of the
two black shielding wires is not necessary for this measurement
method.
Measurement of volume resistance (Rv)
Connect the BNC plug ends of the wires to the device and the
connector of one of the red measuring wires to the red socket of
one of the electrodes. Connect the other red measuring wire to
the conductive material under the measured item. The use of the
black two shielding wires is not necessary for this measurement
method.

Turning on
Turn on the device with the “On/O” button. After switching on, a text similar to the
following appears on the screen containing the device’s data:
AIJGO-61
RESISTANCE METER
S/N: 1234
Ver: v1.02
This is visible for 10 seconds. If you do not want to wait this time, but want to move
on faster, press any button except “On/O”. You will then see a screenshot similar to
the one below:

Measurement
The AIJGO-61 is suitable for measuring a wide resistance range, between 2 Ω and
1 TΩ. This also enables the measurement of equipment grounding resistance and
the resistance of ESD protective worksurfaces to ground. Thus there is no need
to use other resistance meter during ESD qualication or compliance verication
measurements.
Press and hold the “Measure” button until the measurement result is displayed. This
will remain visible until you press the “Measure” button again.
When measuring temperature and humidity, make sure that you do not cover the
sensor on the bottom of the device with your hands or other objects, and do not
place the device on a cooled or heated surface, as this may aect the measurement
results.
Storing measurement results
The measurement results can be stored by pressing and holding the “MODE” button,
after this a message is shown on the display for 3 seconds. If any blank space is still
available in the measurement list, a message similar to the following will be displayed:

VALUES STORED
LIST POS: x
7
The value of x indicates the position in the measurement list where the measured
resistance value and the associated temperature and humidity data are placed. The
list can contain up to 20 measurement positions. Once full, it is not possible to store
any more results. In this case, the following message will appear after a long press on
the “MODE” button:
LIST FULL
When the list is full, it is only possible to store another measurement result after
deleting the list, which can only be done by a computer.
Management of measurement results on computer
An AIJGO-61 product can be connected to a computer with a USB-A to mini USB-B
cable. To manage the measurement results on a computer, the driver program
supplied with the device must be installed, which assigns a virtual serial port to the
resistance meter. To do this, run the application „CDM v2.08.30 WHQL Certied.exe”
as administrator which is on the supplied pendrive (Right mouse button -> Run as
administrator). Once the installation is completed, launch the terminal program
(termite-3.1.exe), also available from the pendrive. The application will start after the
installation. You can use the shortcut in the Start menu to launch it later (it is listed
under the name “Termite”).
When the terminal program is started, a window similar to the following picture
appears:

Click on the “Settings” button and congure your program as follows:
The “Port” eld must contain the virtual serial port number assigned to the device
for proper operation.
Two commands can be used in the program to manage the stored data of an
AIJGO-61 product, these are “LIST” and “DELETE”. The commands can be sent by
pressing the “enter” key after typing them. The following is a picture of the terminal
program after the user has retrieved a stored list with the “LIST” command, deleted it
with the “DELETE” command, and then started a new retrieval with a repeated “LIST”
command.
The listed data can be selected in the terminal program window and copied to
somewhere else if necessary.

Maintenance
Replacement of the batteries
If the batteries are discharged, a screenshot similar to the following will be displayed:
31.6 kΩ
LO W B AT TE RY
24.5°C 42.1%RH
In this case the measuring instrument is automatically set to 10 V measuring voltage.
You can remove the cover plate by unscrewing two screws on the back of the meter
to change the batteries. Be sure to place them in the correct direction to avoid
possible circuit damage.
Safety instructions
The measuring instrument uses 10 V, 100 V or 500 V measuring voltage between the
electrode connections. The output current is limited to 1 mA, nevertheless do not
touch the electrodes when measuring with the instrument.
Calibration
Calibration of the device is recommended once in every 2 years.
The images in this document are for information purposes only. The design, the accessories, the technical
specications and various details of the product can be changed. We reserve the right to sell such changed
product without notice. In case of improper use other than as described in this documentation or in case of
modication of the product which D és Tsa. Bt. has not given its written consent, our company may reject any
warranty claims.
