Specify how you wish the values for the recorded data for each channel’s input voltage range to
be displayed. Decide whether to use 2 voltage points to convert the scale or to use the conversion
equation of y=Ax+B. It is also possible to set in what unit you wish to view the data in the Graph.

Specify 2 points

Taking into account the voltage input range of each channel, specify 2 points at which voltage data
be taken and assign values to those points to reflect the scale you have chosen.

NOTE:

It is possible to enter decimals or minus values. However
do not enter values that would result in the slope being 0.

Make sure to make settings for the slope of the conversion
equation, such that the y-intercept is in a range of –9,999
to +9,999.

Use y=Ax+B

Do not specify 2 points, but enter a simple equation for conversion.

NOTE:

It is possible to enter decimals or minus values. However
do not enter values that would result in the slope being 0.

Make sure to enter values for A and B that are between
–9,999 and +9,999.

Troubleshooting

Distributed by MicroDAQ.com, Ltd. www.MicroDAQ.com [phone]

Q:

I can not communicate with my computer using serial (RS-232C)
communication, what should I do?

A:

Please confirm the following items.

Check the Main Unit

• Check to make sure that there is enough battery power and that the power of the
main unit is ON.

• Check the connection between the computer and the Unit.

• Check to make sure that the Unit is connected to the Serial Port (RS-232C) and
not connected to a different type of communication port (printer or other).

• If you are using a USB-Serial Adaptor, check to make sure that it is a Operational
Guaranteed Product

Check your Computer

• Make sure that the serial port settings are correct and that the port has not been
rendered unusable by the settings.

• With some computers, especially all-in-one computers the serial port serves as
the modem jack.

• Use the Device Manager to check whether the COM port can be used or not.(see
p.45)

• If you are using a USB-Serial adaptor cable, use the Device Manager to check
that the driver has been properly installed. If the driver is not installed properly,
contact the manufacturer of the USB-Serial adaptor cable being used.

• Check to make sure that the serial port has not been rendered unusable by the
BIOS setting.

• Sometimes communication will not work if a switch has been added to the serial
port (RS-232C) or an extension cable has been added to the communication
cable.

• If you have a computer with energy saving function settings, make sure that the
serial port has not been turned off.

• If the PC has two serial ports, try connecting the communication cable to the other
port and try communicating again.

• Check to see if some other communication software is in use.

• If you have access to another computer, try seeing if communication works with
the other computer.

If none of the above is the cause, there may be a malfunction or product failure.
Please contact your local dealer.

* How to check your Communication Port?

Distributed by MicroDAQ.com, Ltd. www.MicroDAQ.com [phone]

In the Device Manager it is possible to check whether the communication port is
usable or not.

If Usable: If Not Usable:

An "!", an "x" or an "arrow" will appear

If you are using a USB-Serial Adaptor:

If Usable: If Not Usable:

Under "Other Devices" an "!", an "x" or
an "arrow" will appear.

For details about checking a communication port, see below.

1.

Open the [Control panel]-[Device Manager].

For Windows 8:

By moving the mouse cursor to the left bottom corner of the desktop screen, a miniaturized

Start Window will appear. Right click to open the pop-up menu and select [Device Manager].

2.

In the [Device Manager], click on [Port (COM&LPT)] and check to see if

under that appears [Com Port (COM1)] or [Com Port (COM2)].
If a port appears, it should be usable.

45

3.

Distributed by MicroDAQ.com, Ltd. www.MicroDAQ.com [phone]

If an "!", an "x" or an "arrow" appears, the port is not usable.

To find out details about any communication
port with an "!", an "x" or an "arrow" mark, right
click on the port and select [Properties].

Q:I can’t get the communication cable connected to the computer. What
should I do?

A: Please connect the communication cable provided with the Voltage Logger

into the serial port of your computer (D-SUB 9 pin male connector).

NOTE:

Please use only straight adapters.

, If the connector on your computer is a D-SUB 9 pin male then there is no need for an adapter.

, If the connector on your computer is a D-SUB 25 pin female then use an adapter (D-SUB 25 pin

male to a D-SUB 9 pin male).

, If the connector on your computer is a Half pitch 14 pin female then use the adapter (Half pitch 14

pin male to a D-SUB 9 pin male) or a combination (Half pitch 14 pin male to D-SUB 25 pin male)
and (D-SUB 25 pin female to a D-SUB 9 pin male).

Q:The date and the time of the recorded data are different from the
actual date and time. Why?

A: The Voltage Logger has no internal clock. When you set up a programmed
recording start or when you download data, the date and time that are shown are
taken form your computer’s clock. If your computer’s clock is not correct, it will affect
the recorded data.

Q:Is my data being backed up?

A: If the battery power becomes weak during operation a battery warning mark

will appear on the LCD. If the power is left to become even weaker, the unit

will stop operation but all data will remain backed up.
