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. 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.

 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 TEMPERATURES [LOGGING FUNCTION] (P. 17).

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.

4.3 Judging Measured Temperatures

The judgment criteria of a measured temperature is described by referring to the following example.

• Measured object: Hot water

• Tag number: 2 (tag name: PAN02)

• Judgment criteria: Judgment point of high limit temperature 90.0 °C

Judgment point of low limit temperature 50.0 °C

 Procedures

1. Turn on the power. The measurement screen appears on the LCD.

2. Press the > key. Tag name is displayed in the message column.

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.

Personal Computer: DOS/V PC and PC98-NX Series loaded with USB port (USB 2.0/1.1) OS: Windows XP Home Edition/Professional, Windows Me,

Windows 2000 Professional

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. When this OS corresponds to Windows XP or Windows 2000, start the windows system with the DP-700B unconnected to log on as a user having the authority of computer manager. First start the system, and then connect the PC to the DP-700B.

DP-700B

(Right view)

* 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..

Remove the USB connector cap.

9.2 Storing Data

Open “My computer” of Windows to double click the “Removable disk” 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)

 LOG_.CSV (Recorded temperature data)

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.

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.

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
