2. PREPARATION BEFORE USE
This chapter describes preparations necessary for operating this instrument for the first time.
2.1 Loading Battery
Procedures
1. Loosen the battery cover.
Turn the cover with a coin.
2. Remove the battery cover.
3. Load a battery without mistaking its polarity.
+
4. Then, firmly tighten the battery cover.
Alkaline battery (LR6)
Insufficient tightening cannot assure the effect of water resistance (DP-700A: Equal to
IP67, DP-700B: Equal to IP54).
After the battery is loaded, the instrument is ready to be
reset-started.
The function menu “Utility (Fn0)” for setting the
dominical year is displayed on the LCD screen. If no
dominical year is set, no calendar function can be used.
Always set the year if the calendar function is used.

3.2 Measuring Temperatures
To measure temperatures, insert the sensor into or contact it with the measured object. When
measuring temperatures, handle the sensor as instructed in the following.
In order to prevent injuries, never direct the sensor tip toward a
person.
In order to prevent burning or frostbite, do not touch the sensor
during or just after its use in the high or low temperature
environment.
CAUTION
WARNING
!
Use the sensor within its temperature measuring range.
Firmly insert the sensor cable into the sensor connector of the mainframe.
If the sensor gets stained, wipe it with a clean cloth.
Example of display screen during measurement:
When a measured object is at a surface temperature of 90.0 °C
It is possible to record the measured temperature and date in the memory.
For the data recording (logging) method, see 5. RECORDING MEASURED

4. JUDGING MEASURED TEMPERATURES [SIMPLIFIED JUDGING FUNCTION]
This chapter describes settings and procedures to judge measured temperatures using the
simplified judging function.
Before using the simplified judging function, register tag names (measured object names) and
also set judgment criteria (judgment points of high and low temperatures). The registration
and setting are made on the function menu “TAG Setup (Fn2).”
What is the simplified judging function?
This function is for judging whether or not measured temperatures are within the
judgment criteria preset (judgment points of high and low temperatures) and then
check judgment results according to simplified judgment symbols.
