The FULL mark appears when 8000 units of data have been recorded
in ONETIME Mode.This indicates that recording has stopped and it is
important to download the data into your computer as soon as possible.
●OVERTHE MEASURABLE RANGE
The Hi mark indicates that the temperature is over the measurable range
of 600℃.
●BELOWTHE MEASURABLE RANGE
The Lo mark indicates that the temperature is below the measurable
range of
- 200℃.
●SLEEP MODE
The battery lamp will begin to blink when power is very low, recording

Replacing the Battery
●The main unit can remain in working condition for about 2 minutes without a battery.
●Battery life depends on many conditions including the recording environment, the recording inter-
val, the amount of communication, the surrounding temperature, and others.This explanation is
based on using a new battery and in no way should be taken as a guarantee of battery life.
Recording Int. of more than
2 sec’s. Recording Int. of 1 second
Maximum 8 months Maximum 5 monthsTime before BAT lamp (warning) appears.
◆The following chart can give you a general idea as to battery life.
Time to change the battery
◆Once the BAT lamp appears on the display make sure to change the battery as soon as
possible. If you change the battery before the BAT lamp begins to blink, recording will
continue uninterrupted and without any loss of data.
◆If the batteries go completely dead, all recorded data and recording settings will be lost,
so please be attentive to the BAT lamp.
After changing the battery
◆If you changed the battery when the BAT lamp was on.
◆If you changed the battery when the BAT lamp was blinking.
Change battery Returns to same condition as before lamp
appeared. Recording continues without
trouble.
Change battery The power automatically goes off.Make
sure to turn back on.
If the BAT lamp is blinking make sure to download all data as soon as possible.If you
press the [REC/STOP] button on the main unit a new recording session will begin
and all previously recorded data will be automatically deleted.

Troubleshooting
Q
::
::
: I can’t get the communication cable connected to the computer.What should I do?
A：Please connect the communication cable provided with the Thermo Recorder into the
serial port of your computer (D-SUB 9 pin male connector). If for some reason you
can not connect directly, please use an appropriate adapter (gender changer plug)
as explained below.
・・
・・
・If the connector on your computer is a D-SUB 9-pin male then there is no need for
an adapter.
・・
・・
・If the connector on your computer is a D-SUB 25 pin female then use an adapter
(D-SUB 25 pin male to a D-SUB 9 pin male)
・・
・・
・If the connector on your computer is a Half pitch 14 pin female then use the adapter
(Half pitch 14 pin male to a D-SUB 9 pin male) or a combination (Half pitch 14 pin
male to D-SUB 25 pin male) and (D-SUB 25 pin female to a D-SUB 9 pin male).
Q
::
::
: I can’t download settings and / or data from theThermo Recorder to my computer.
What should I do?
A：Check to make sure that the connection is proper.Communication will take place
only through the serial port (RS-232C) and will not work through the printer port or
any other.
A：Check to make sure that you can control the Thermo Recorder with the software.
A：Make sure that the serial port has been selected correctly in the [Communication]
pull down menu in the software. Please check which port you are connected to
(COM1-COM4) and select appropriately.
A：If you have access to another computer try to see if you can download using it.
A：If you have a computer with energy saving function settings, make sure that the serial
port has not been turned off.Especially on NEC brand PC98 notebook computers the
default setting may be such.
A：If your computer is a DOS/V type check to make sure that the serial port has not been
rendered unusable by the BIOS setting.
A：If your computer is Windows 95/98 please make sure that the serial port setting has
not been made to render it unusable.With many all in one computers it serves as the
modem jack.
Examples of various serial ports:
《 D-SUB 25 pin female 》《 D-SUB 9 pin male 》 《 Half pitch 14 pin female
》
《How to check》
①In Windows 95/98 Open the [System] file in the [Control Panel] (Figure 1).
《Figure 1 Control Panel》
《Figure 2 [Device Manager]》《Figure 3 [Port (COM&LPT)] enlarged view》
・To find out more details about the port in question you can double click on [！] to
open [Properties] and a window giving details about that port will appear.
②Open the [Device Manager] file in the [System Properties] window and double click
on [Port (COM&LPT)] (Figure2) to open. Check to see if [Com Port (COM1)] and/or
[Com Port (COM2)] are displayed.If so they should be usable unless they have a [!]
or a [x] (Figure 3) mark on them, If such a mark exists, that port is unusable.If you
can not use a communication port please contact your computer’s maker.
Figure 4 Case where modem is using Port (COM2)
A：If your computer has an internal modem, make sure that the communication port is
not being used by it. In some cases even though no settings appear for the commu-
nication port, it can not be used. Check to see which port is being used by the
modem.

25 26
A：Sometimes communication will not work if an extension cable has been added to the
communication cable or if a switch has been added to the serial port (RS-232C).
A：Check to see if some other communication software is in use.
A：Most desktop models have two serial ports, try changing the plug to the other port
and change the settings.
Q
::
::
: The images are hanging off the display screen.What should I do ?
A：The display should be set at a resolution of 640x480 dpi or higher.
Q
::
::
: The date and the time of the recorded data are different from the actual date and
time.What should I do?
A：The Thermo Recorder takes the date and time from your computer when it is set
up. Make sure that the date and time are correct on your computer.
Q
：：
：：
： Is the data backed up automatically?
A：If the battery power goes low while recording the BAT lamp will come on. If the
power decreases even more, recording will be ceased and a backup of the re-
corded data will be made.
