Cables
See section 1.3.
2.3 Other equipment
needed
Digital Multimeter (DMM)
The system is designed for use together with Agilent
34401A (connected via serial / COM-port) or Agilent
34410A (LAN / Ethernet connected). The system can
also be used with Keysight 34461A (LAN / Ethernet
connected). Probably also Keysight 34465A, but this
has not been tested.
Computer
PC with USB port and COM port or Ethernet port,
depending on type of DMM (see above).
Cable for connection between PC and DMM, depend-
ing on type of instrument (serial null modem cable or
Ethernet cable).
Note: If the PC is of an older model, and LAN /
Ethernet connected DMM is used, a crossover
Ethernet cable may be required.

3Operation
3.1 Installing SW
The software is installed from the USB drive. There are
two folders in the USB drive. Choose folder according
to the DMM that you have.
A] If you have a DMM type 34401A or 34410A,
open folder OLD_(Agilent).
B] If you have a DMM type 34461A, open folder
NEW_(Keysight).
1] Open folder BVM CAL SW, then double-click
setup.exe to install the software.
3.2 Connect and setup
Make connections as shown in the diagram in fig-
ure3.2.1. Supported multimeters are: Agilent 34401A
serial connected or Agilent 34410A network con-
nected.
For use with Keysight 34461A, see figure 3.2.2
Note A null modem cable is needed for connection
of the Digital Multimeter.
How to set COM port for the
digital multimeter (DMM) (Agilent
34401A) or other equivalent
instrument
This step is optional.
1] Enter the COM port number.

3 OPERATION

2] If you don’t enter a COM port number, the
software will search the PC for the COM port
that the DMM is connected to.
3] If the automatic search for right com port does
not work you can set it manually.
4] In MS Windows, open the “Control Panel”.
5] Select “Device Manager”.
6] Right-click on the port you want and select
“Properties”, “Port Settings”, “Advanced”,
Select the number on the COM-port (from
1-15).
Note The BVM Cal System can only handle COM-
ports from 1 to 15.
How to set IP address for the
digital multimeter (DMM) (Agilent
34410A or Keysight 34461A
This step is optional, but recommended.
1] Enter DMM IP address in BVM calib.
2] If you don’t enter an IP address, the software
will search for a connected DMM. Which will
take some time.
3] If the automatic search for right IP address
does not work you can set it manually.
4] It can be found by either starting PC Com-
mand window, then typing command
“ipconfig”, or by entering the menu on the
DMM (press buttons Shift, then Display (Util-
ity), then find LAN settings, or refer to DMM
User’s manual).
The IP address is a series of digits separated
by dots. It is normally 169.254.aa.bb, where
aa and bb are numbers between 0 and 255.
Note It takes up to one minute to establish connec-
tion between PC and DMM.
5] Please refer to the manual for the DMM to
find out how to get the IP-address for the
instrument.

3 OPERATION

3.3 Calibration
1] Start the BVMcalib SW as administrator.
2] Press “New Unit”.
3] Select connection type by clicking ComPort
or Ethernet.
Note If the port for the Digital Multimeter (DMM)
is not found you shall follow the steps 3 to 5
below.
The calibration will proceed and data are presented
subsequently.
When calibration is ready and if it is approved it is
automatically accepted and the new data are saved.
Logfiles are saved in C:/ProgramFiles(x86)/BVMcalib.
4] Click “Yes”.
5] Click “Yes”.
The calibration will start.
6] Disconnect the calibrated BVM unit and con-
nect the next BVM unit.
If the BVM unit does not pass the calibration the
faulty value will be highlighted with red, see example
below.
7] You can try to run the calibration once
again to see if you get the same result. Click
“Reject” and then “New Unit” to run a new
calibration.
A defective unit should be replaced.

3.4 Error messages
Bad connection
Here are some examples showing error messages
when a connecetion is lost.
1] Check all leads and connections.
Battery failure
If the battery power is to weak you will get the fol-
lowing error message.
1] Check batteries and replace with new batter-
ies.

3.5 System calibration
Every six months the BVM CAL Ref unit should be
calibrated. The system can calibrate itself and is done
as follows.
1] Connect in the same way as for a standard
calibration but shift positions for CAL Ref
BVM and BVM unit.
2] Run a normal calibration.
3] Shift back to right position for the CAL Ref.
