9. Testlink HH520 SOFTWARE

9.1 The HH520 package contains:

 Software CD disk
 Micro USB cable

9.2 System Required:

Windows XP/ VISTA/ Windows 7/ Windows 8/ Windows 10

9.3 Minimum Hardware Required:

 PC or laptop with CD-ROM drive.
 At least 50 MB hard disk space available to install HH520.
 Recommended screen resolution 1024X768 or above.

9.4 Tutorial - Quick Start to Use HH520:

Recording real time data in waveform:

(1) Power on the 4 Channel Thermometer first and connect it to a PC USB port with the cable,
(2) Start HH520 program.
(3) If the connection is successful the panel will display

the same value as the 4 Channel Thermometer. If
fail to connect the meter with PC, it will display " No
Connection " on the panel window in HH520.

(4) Select sampling rate from Real-Time Graph window.

(5) When the connection is successful, click “ Real Time | run ” or

start recording real time data and there will be a waveform on the Real Time Graph
Window.

(6) Click “ Real Time | Stop ” or

to stop recording.

9.5 How to save the recorded real time data to a file?

(1) Click the graph window you want to save and the graph window will become active, then

choose File | Save from main menu or click from the tool bar .

11

DATALOGGER THERMOMETER

(2) There will be a save dialog window for you to choose the file name and file type to save.

There are three types of file format you can choose, binary file(*.ghf), text file(*.txt) and
EXCEL format file(*.csv). The *.ghf file use much fewer disk space to save the data than
the other two file formats, but it can only be used in HH520. Text file can be opened by
HH520 and any other word processor program like word, notepad etc. EXCEL format file
can be opened by HH520 and Microsoft EXCEL.

Note: If decimal separator is comma in your country, this file format will be disabled,
because .CSV file also use comma to be data separator. For example 78,6 will become 78
and 6 in EXCEL )

9.9 Frequently Asked Question:

(1) How to uninstall HH520 ?
Answer: Uninstall HH520 by launching the Add/Remove Programs applet out of the Control

Panel, highlighting the HH520, and clicking on the Add/Remove... push button, then it will
remove the HH520 folder and files from your computer.

(2) How to zoom the graph?
Answer: Press the left mouse button and drag the cursor to select the new extents, then

release the mouse button.

(3) When I setup the real time sampling with a fast rate(eg. 1 sec), Some of the
sampling data might be lost.

Answer: This might be caused by slow response time of the PC interface. For better result,

the user may close the panel window.

10. Maintenance

In order to ensure the accuracy of the thermometer for a longer period of time you should
calibrate it once a year.

Clean the device and the window of the display with a clean, lint-free, antistatic and dry cleaning
cloth.

Do no use cleaning agents that contain carbon or benzenes, alcohol or anything
similar to clean the product since these substances damage the surface of the
measuring instrument. Moreover, these fumes are hazardous to health and explosive.
Do not use tools with sharp edges, screwdrivers, metal brushes or anything similar to
clean the device.
