About How Data is Recorded

The MCR-4V records measurement data to its internal memory. A
recording session is one cycle from recording start to stop, and the
MCR-4V can record multiple sessions. The number of recording
sessions and number of data readings which can be recorded depends
upon the number of channels, the recording interval and other settings.
In the “n”th recording session, the remaining memory space is used for
recording.

EX: When logging capacity is lled during the 5th recording session:

taken during the set recording interval.

Ave.(Value) Fine: This records the average value for measurements at
even shorter measurement interval.

IMPORTANT

- When recording average values, the rst recorded value is invalid because an average
cannot be calculated.

- If the Preheat function has been set to ON, then only recording of instantaneous values
can be selected.

- Recording in the “Ave.Fine” method consumes more power than other methods,
resulting in a shorter battery life.

the recording interval to turn sensors ON before and OFF after measuring
and recording.

Other than the sensor ON/OFF function, preheat can also be used to
control transient-load battery, lights, heater, and transient signals.

Preheat Time

When using the preheat function, this stands for the length of time to
send current to the sensor before measurement and recording is set to
occur. When setting the preheat time that is equivalent to or longer than
the recording interval, current will be supplied to the sensor at all times.

Troubleshooting

Q1.

The computer does not seem to recognize the MCR-4V,
why not?

A1.

Please check the following:

Check the MCR-4V

Check the USB connection between the computer and the MCR-4V.

Check the Computer

• Make sure that the software has been installed properly and is
working.

• The USB driver installation may not have been installed correctly.
Please see [Help for Unit Recognition Failure] in the Help menu,
and check the USB driver.

• Connect a different USB device (mouse, digital camera, etc...)
other than the MCR-4V to your computer and see if it operates
properly.

• If your computer has more than one USB port, try connecting the
USB cable to a different port.

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

If after checking and trying the above there is no improvement
please contact the distributor where the product was purchased.

Q2.

The rst reading of recorded data is invalid data, why?

A2.

One of two scenarios is possible:

• When recording average values, the rst recorded value is invalid
because an average cannot be calculated.

• When the Preheat function has been set to ON (recording method:

56

instantaneous values only) and the preheat time is set to longer
than the waiting time before recording start, the rst data reading
will be invalid because preheating has not been completed.

Q3.

Is it possible to change the batteries while the unit is in
operation?

A3.

If the unit is connected to an AC adaptor or some other external
power source, it is possible to change the batteries. If only
batteries are being used as the power source, it is necessary to
stop recording before changing the batteries.

Q4.

Is it possible to adjust or alter recorded data that has
been downloaded by the MCR-4V?

A4.

In order to maintain the integrity and trustworthiness of the
recorded data, the software has been designed to not allow
modications to be carried out on actual recorded data.
If it is necessary to edit recorded data, in “T&D Graph” save the
data to text le and use a common spreadsheet software such
as Excel to edit the text le data.

Q5.

I get a “Write Error” when I try to export recorded data to
an SD memory card, what should I do?

A5.

Please check the following:

• Make sure the write protection switch on the SD memory card is
unlocked.

• Check if your SD memory card is supported by the MCR-4V. (See
p.38)

• Perform a “Memory Card Test”. (See p.44)

• Perform a “Quick Format” for your SD card. (See p.44)

If after checking and trying the above you still get an error
message, please contact the distributor where the product was
purchased.
