1． INTRODUCTION

1.1 Paperless Recorder

① This recorder displays measured data in real time on the liquid crystal display. It is a paperless

type that is also capable of saving the measured data to a SD memory card (hereinafter referred to
as SD card). It can operate easily with the liquid crystal with the touch panel.

② It can set up to 12 channels for the input types such as thermocouple, resistance bulb, and DC

voltage (or current).

③ It allows the measured data saved to the SD card to be displayed on the display unit.

Use of the support software attached to the recorder allows the saved data to be displayed on a
personal computer.

1.2 Accessory check

Upon receiving the recorder unit, check the appearance for damage, and if the correct quantity of the
accessories are supplied. Please contact the shop that purchases it or our salesman when there is a
part not suitable by any chance.

・Please confirm it is a correct direction and the firm insertion when it installs it. The

recorder cannot recognize the SD card when forcibly inserting it in a wrong direction.
Moreover, it causes the breakdown of the SD card and the main body of the recorder.
Please note that the damage of the equipment when it reversely inserts it becomes off the
subject of the guarantee.
Please do not turn off power in recording of the SD card, and do not detach the SD card.

・

Data might damage, and delete it.

・The data preserved on the card recommends the backup to be booked once a month.

When the SD card breaks, important recorded data is lost. Please book the backup.

・

MiniSD and the microSD card cannot be used. The use of miniSD and the microSD card
