Introduction
Congratulations on your purchase of this
multiple function PDF datalogger.
This datalogger is designed for monitoring
temperature or temperature with humidity
subject to quality control requirement.
Temperature and humidity measurements
are saved throughout the entire duration of
the measurement period.
This datalogger is equipped with a user
defined programming function.
The measurement report output is
implemented using a PDF file and an
Excel file, no unique software,
and no USB driver are required.
Read through the instruction manual
before using this logger. The logger is
calibrated before shipment.
1.USB2.0 plug & play connector. USB driver is
not required.
2.LED indicator:
Low/High
: Red LED blinks every 10 seconds when the
measuring set limit value is exceeded during record.
OK:
When the logging function is started, the green LED
blinks once every 10 seconds when green LED blinks
once every 10 seconds when there is no alarm occurs.
3.NTC thermistor for temperature measuring and
capacitive humidity sensor for humidity measuring.
4.External probe socket in models with external probe port
5.LCD (Liquid Crystal Display).

c. T1 is air temperature, T2 is external probe
temperature
d. H or L displays when measuring set limit
value is exceed.
e. MX or MI display when checking MAX or MIN
value from logged data.
f. Low battery icon flashes on display every
second when battery level is too low to accurately
measure and log data.
6.Battery cover, operated by 2 pcs CR2032 batteries.
Use coin and follow up the direction indicator to open

MARK key:
To mark an event manually during the measurement
period, press the MARK button for 2 seconds until the
measured data flash three times. This MARK function
is usually used when there is a transition, from one
location to another. At most 8 marks will be identified
in the PDF report.
Short press MARK button any time can also display
the leftover battery life time as a quick reference.
However, precise battery life time is still decided by
operation condition & battery brand.
9.MAX/MIN key:
Press key to check the MAX or MIN data of all logged
data.
10.Waterproof cover and stand:
To provide USB plug waterproof feature, put on this
cover and slightly rotate it to make it tight. To make
logger stand on desktop, rotate this cover to suitable
supporting angle.

Step1 Configuring the data logger
It is possible to make configuration changes at
anytime before the logging function is started.
Once the logger is started, configuration
changes cannot be made unless stopping the
logging first. If the logger is locked with a
Password, the Password is required to make
configuration changes.
- Press ON/OFF to power on the logger
- Connect the data logger to a PC via the USB
port. The green LED is ON while building the
connection with computer.
- Windows file display window will appear.
- If the correct file folder is not open, click on
Folder to view files.
- Open the file " PDF Logger Configuration
Tool. exe".
- The default language is English. The user may
change it to one of several alternate languages.
There are English, German, French, Italian,
Spanish and Portuguese.
- To review the instruction manual, you may click
"Manual" to open the manual PDF file.
- The user can check the calibration report for the
logger by selecting the PDF file named "Calibration
Certificate".
- User programmable parameters are as follows:
★
Sampling rate
Select the sampling interval you need from 30
seconds to 2 hours.
★
Alarm Limits
Select the alarm threshold values. For example: if
2 - 8 deg C is selected, it means that an alarm
condition will occur below 2 deg C, or above 8 deg C.
The programmable alarm limit of each parameter is
limited to one decimal. To summarize, to activate a
alarm when 30 min average value of hazardous alarm
delay period is higher than 8
℃
, please program the
alarm delay as 30 mins, alarm type as cumulative and
range as 2~8°C
★
Time zone
Before programming the logger the user must assure
that the PC is set for the correct time zone. The logger
will auto synchronize to the time zone of the PC, when
Save is pressed. Time zone changes over the transit
distance are not adjusted in the logged data.
The default value of above parameters are:
Sampling rate: 5 min Alarm Type: Disable
Start delay: 0 min Alarm delay: 0 min
Temp. Unit: °C Alarm Limits:
Password: disable Temp. blank
Company Name: blank Ext. T: blank
Language: English RH: blank
Once all the programming is done, press "Save" to
confirm the setting and then you may close the setup
window and remove the logger from PC USB port.
a. Measured temperature or humidity. LCD updates
and interexchange every 5 seconds.
b. REC flashes every second when logger is in
logging mode. While logger is programmed with
start delay, REC displays but doesn’t flash during
the standby status.
Operation
NOTE:
1. Adobe Reader software is required.
2. Program the logger and generate the PDF
and Excel report at room temperature.
For example: if the logger is removed from a
freezer, it should be allowed to return to the
ambient room temperature before generating
the PDF report temperature.
3. The executable file for programming the
logger is named: PDF Logger Configuration Tool
★
Start delay
Select the start delay from 0 min to 24 hours.
For example: If the delay is 5 minutes, and the
sampling rate is 10 minutes, the real time to log the
first temperature measurement is 5 minutes after
the START button is pressed. All measurements
after the first measurement will be at a 10 minute
(or selected) interval.
★
Temperature Unit of Measurement (UoM)
Select the temperature UoM that will be displayed
on the PDF report. The selections are Celsius, or
Fahrenheit. Celsius is the default.
★
Password
The Password function is default OFF. The user
may enable it to prevent unauthorized
reprogramming prior to pressing the START button.
A Password may have up to 16 alpha or numeric
characters.
★
Company Name
A user defined name, or descriptor, can be input
under Company Name. It will be displayed on the
PDF report as the Title, with a maximum of 20
characters.
★
Alarm types
Regardless of the Alarm Type, if the red LED is
triggered, it won’t stop even the reading return to
normal range or logging is stopped. The way to
stop red alarm LED is to plug logger into computer
to generate report or power off the logger.
Single: an alarm is triggered immediately when the
measured value exceeds the alarm threshold.
Cumulative: an alarm is not triggered when the
measured value exceeds the alarm threshold, but
only once the overall average value during alarm
delay duration exceeds the alarm threshold.
Disable: No alarm function during the logging
process
★
Alarm delay
The preset alarm delay interval for a single alarm
type is always ZERO.
The adjustable alarm delay interval for a cumulative
alarm type can be 5 minutes to 2 hours.
Step2 Start the logging
- Press "START" key for 5 seconds when you want to
start the logging.
-“REC” will appear and flash on LCD to indicate the
logging is activated. Measured parameters update
and interexchange on LCD every 10 seconds.
- If Logger is programmed as Start delay, after
pressing the start key, the “REC” will appear
(not flashing) to show the logging is started and in
standby status.
-During the logging, the green LED will blink every
10 seconds if there is no alarm occurred. If any, it
turns into flashing red LED.
-If the red LED is triggered, it won’t stop even the
reading return to normal range or logging is
stopped. The way to stop red alarm LED is to
plug logger into computer to generate report or
power off the logger.
