: When the “MEMO No.” is lit on the display, the measured value indicated on the
PV display or each HOLD value is memorized by pressing the SAVE/ key
(hereinafter
key). When thermo-hygro sensor is connected, the current
values (temperature and humidity) are indicated by turns at every 1.5 seconds.

4.1 How to insert (remove) the batteries
Explanation written below is based on the condition that
the power supply to DFT is OFF. Such being the case,
if the power supply to DFT is ON, turn the power OFF by
pressing the POWER key.
1. Push the battery cover up in the direction indicated by
the arrow (1) then swing the cover open in the direction
indicated by arrow (2). The battery cover opens. (Fig.4.1-1)
2. When inserting the batteries
Insert the batteries to the direction as shown in the
battery case. Insert as indicated by (3) and then swing
them in (4). (Fig.4.1-2) If batteries are inserted correctly,
“DFT-700” is indicated on the LCD display for 5 seconds
and then returns to the power switches OFF.
When removing the batteries
After making sure that power is OFF, push + side of the
batteries up in the direction indicated by (5) then swing
them in the direction indicated by (6) and remove them.
(Fig. 3-1)
(Fig.4.1-3)
3. After setting batteries in the battery case, insert the case cover in the direction indicated by (7) then swing
it closed (8). Hold the battery case cover until a “Click” is heard.
* Even if batteries are changed, each setting value and memory data are not erased.

4.2 How to connect sensors
Insert the sensor side plug (hereinafter plug) to the measuring
side receptacle (hereinafter receptacle).
When inserting the plug, hold the (1) section of the plug.
