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:
1st

2,000

In Endless mode,
data will be overwritten from the
beginning of the 5th recording
session and recording will continue.
In One-Time mode,
recording will stop.

* If the memory capacity has not reached full, up to 30 recording sessions can be
made.

Overview
Using SD Memory Cards
It is not only possible to transfer data stored in the internal memory to
an SD memory card, but it is also possible to automatically backup data
while recording in endless mode. Operations related to the use of an SD
memory card are as follows:
Record in internal
memory
Copy data to a
memory card
Copy
to a PC
Exporting Data while Recording is OFF (Manual Saving) See p.38 for
details
[Data List]—[Export Selctd Data]

Exporting Data while Endless Recording is ON (Manual Saving /
Automatic Saving) See p.42 for details
[Data List]—[Expt Curr Data Now]
[Data List]—[Auto Data Export]
IMPORTANT
- Memory cards are not included. Please purchase separately.
- Measurement data cannot be directly recorded into a memory card.
- Before inserting an SD memory card into the device, make sure to switch off write
protection on the memory card.
- Exporting data to the memory card will not erase it from the device’s internal memory.
Delete recorded data in the device as necessary.
Supported Memory Cards
- SD Memory Cards
- SDHC Memory Cards
IMPORTANT
- SDXC memory cards cannot be used.
- It is possible to run a quick test to see if your memory card works in. See p.44 for details.

Using MCR-4V
Installing the Battery
Remove the battery cover from the back of the device, and insert the
supplied two AA alkaline batteries as shown in the gure below.
After the batteries are inserted, the [Please set the clock] message will
appear on the LCD.
IMPORTANT
- Make sure to use new batteries of the same kind.
- Make sure not to mistake + / -.
- Do not insert or change batteries with wet hands.
- Be sure to completely close the cover.
- The MCR-4V cannot recharge batteries.
Usable Power Sources
- AA Alkaline Batteries
- AA Ni-MH Batteries
- AC Adapter (USB type)
- USB Bus Power
Changing the Batteries
If the battery runs down before it is replaced, MCR-4V will automatically
stop recording to protect data. Check the battery mark (see the previous
page) and change batteries as necessary.
IMPORTANT
- To protect data, please stop recording rst before changing batteries. Not doing so
may result in loss of data being recorded.
- When you wish to replace batteries while recording is in progress, make sure to
connect the USB cable to your PC for USB bus power.
- If the MCR-4V runs out of power while processing data on a SD memory card, the data
on the card may be corrupted.
