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.

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.

Pressing the ESC key twice can display the measurement screen.

3. BASIC OPERATION

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.

WARNING

!

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

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

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.

9. MANAGING DATA BY PC
[ONLY FOR DP-700B]

For the DP-700B, it is possible to manage recorded (logging) temperature data, tag and initial
set data stored in the memory by a personal computer with the DP-700B connected to the
USB port of the computer. This chapter describes procedures for connecting the DP-700B to a
personal computer and also for managing stored data.

<System Requirements for a USB Connection>

Personal Computer: PC with USB port (USB 2.0/1.1)
OS: Windows XP (32-bit and 64-bit versions),

Windows Vista (32-bit and 64-bit versions),

Windows 7 (32-bit and 64-bit versions),
Windows 8.1 (32-bit and 64-bit versions),
Windows 10 (32-bit and 64-bit versions)

9.1 Connecting PC to DP-700B

As the DP-700B is operated by the OS standard driver, it can be used only by connecting it to
a PC.

1. The DP-700B is connected to the USB port of a PC using the USB cable attached.
The DP-700B can be connected with the power turned on or off. *

2. The message “ ***USB*** ” is displayed on the bottom of the DP-700B screen to
disable key operation. In addition, data logging stops when being logged.

If the DP-700B is used for the first time, the OS standard driver is automatically
installed. Start the windows system with the DP-700B unconnected to log on as a
user account with administrator privilege. First start the system, and then connect the
PC to the DP-700B.

USB cable length: 1 m

* The DP-700B is compatible with the USB bus power. The power is supplied from the USB port

on the PC side via the USB cable when connected with USB. It is possible to manage data by
connecting USB even with the DP-700B power turned off.

3. Open “Devices and Printers” of Windows to newly add the “USB mass storage device”
icon.

9. MANAGING DATA BY PC [ONLY FOR DP-700B]

9.2 Storing Data

Open “Devices and Printers” of Windows to double click the “USB mass storage device” icon.
Thus, three CSV files in the DP-700B memory area displayed.

LOG_ .CSV: Recorded (logging) temperature data
TAG_ .CSV: Tag setting data
SETUP_ .CSV: Initial setting data

The LOG_ .CSV, TAG_ .CSV and SETUP_ .CSV files are created when the
DP-700B is connected to USB.
As a file name of each file created, characters of identifying each entity (DP-700B)
are entered in . Thus, two or more DP-700B files are identified.

If no temperature data is stored within the DP-700B memory, the LOG_ .CSV file
is not displayed.

LOG_ .CSV (Recorded temperature data)

Recorded (logging) temperature data. Read only file. It can be opened and referred to by table
calculation software such as Excel. In addition, it can be copied it stored at a location other
than the DP-700B using a new name.

CAUTION

Deleting the LOG_ .CSV file also clears all recorded temperature data
within the DP-700B memory. Take care not to delete necessary recorded
temperature data.

If no temperature data is stored within the DP-700B memory, the LOG_ .CSV file
is not displayed.

Contents of file: Memory No., Date, Time, Temperature, Tag No., User No.

Copy data to the hard disk of the PC using Windows Explorer.

9.3 Disconnecting DP-700B from PC

Disconnect the DP-700B from the PC after the PC power is turned off or according to the
following steps.

Do not disconnect the DP-700B from the PC when the file is opened or while the
file is being stored. Malfunction may result.

The DP-700B can be disconnected with the power turned on or off.

The disconnecting procedure is described in “Windows 7.” Icons and windows
displayed differ depending on OS used. For details, refer to the manual for
“Windows.”

1. Check that the file is not opened or it is being stored. Close when the file is opened.

2. Click “Show hidden icons” in the taskbar. The notification area is displayed.

3. Click “Safely Remove Hardware” in the notification area.

4. Click “Eject USB mass storage devices” in the displayed menu.

The displayed contents depend on the number of USB devices
connected to your computer. Carefully click the icon not to select a
wrong device.

5. The “Safely Remove Hardware” icon moves to the notification area. When you see
the message “Safe to remove hardware - The USB mass storage device can now be safely
removed from the computer,” remove the device from your computer.

6. Disconnect the DP-700B from the PC.

10.1 Replace the Battery

If (Battery service life is going to expire) is displayed, immediately replace the battery.

Replace battery: Type LR6 (based on IEC and JIS) alkaline battery, One battery
Battery life: Can be operated for 400 hours continuously (Around the ambient

temperature 23 C). However, the battery service life varies depending
on the operating condition and environment. Therefore, the above service
life period is only for reference.

If the battery is replaced, the instrument is reset-started. Therefore, there are
some data items to be initialized. In addition, for the DP-700A all recorded data
items are deleted. The state of each data when the battery is replaced (when
reset-started) is shown in the following.

10.2 Cleaning

Turn off the power supply before cleaning the instrument.

Moisten a soft cloth with a diluted neutral detergent, completely wring the cloth, then wipe
the instrument with cloth. Do not use a volatile solvent such as paint thinner to clean the
instrument. Deformation or discoloration will occur.

The DP-700A can be washed in flowing water as it has water and dust resistant characteristics
equal to IP67.
However, the DP-700B (Water/dust resistance equal to IP54) cannot be washed in flowing
water.

10.3 Troubleshooting

This section describes probable causes and treatment procedures if any abnormality occurs in
the instrument. For any inquiries, please contact RKC sales office or the agent, to confirm the
specifications of the product.

Prior to replacing the sensor, always turn off the power.
