The Tabular window can be used to record real time data in a table format. The maximum
number of records that the Tabular window can keep will be depending on how many available
memory and hard disk space of the connected computer.
(8)Data Logger
When you have thermometer connected to computer, select "Load Data" to start loading the
recorded data from the thermometer. There will be a progress indicator to show the loading
progress.
If error occurs, just click "Load Data" again.
After the data has been successfully loaded to computer, the left side window shows how many
data sets were loaded and their detailed information (start date, start time, recording rate, and
record numbers).
For example:
10
PCE-HPT 1 THERMOMETER
It will transfer the first data set to graph and tabular on the right side window once you finish
loading recorded data from the thermometer. You can click on at any data set to show its graph
and tabular on the right side window.
You can choose a rectangle area on the graph to zoom in for detail.
The vertical dash line in the graph will match the highlight row in the tabular. When clicking on
another row in the tabular, the vertical dash line will move to the corresponding position to
match the time.
(9)Frequently Asked Question:
Q: I have connected thermometer to computer serial port and turned thermometer on, but it still
shows "NO CONNECTION" ?
A: It could be caused by that all serial port are occupied by other applications. Close all
application, restart your computer, and run PCE-HPT 1 again.
Q: In TABULAR window, I saved a file. Can I use EXCEL to open this file?
A: If the decimal separator is comma (,) in your area, you cannot use CSV file because CSV
file use comma to separate data. This will cause confusion (for example 23,6,C,24.6,C).
However, you can use TXT files instead. It uses tab to separate to data.
(For example: 23.6
C
24.6
C) and it can be accepted in EXCEL.
Q: How to uninstall PCE-HPT 1?
A: Uninstall PCE-HPT 1 by launching the Add/Remove Programs applet out of
the Control Panel, highlighting the PCE-HPT 1, and clicking on the Add/Remove...
button, then it will remove the PCE-HPT 1 folder and files from your computer.

11. POWER PREPARATION
11.1 Battery Loading
Remove the battery cover on the back
and insert one 9V battery.
11.2 Battery Replacement
When the battery voltage drops below
the operating voltage, Low battery
will appear. Replace a
indicator
9 Volt battery immediately to ensure
the unit functions properly.
11.3 AC Adapter Connection
When the AC adapter is used, insert the plugs of the adapter into the DC9V connector on the side
panel.
Note:
When the AC adapter is connected while battery is inserted, the unit will be powered from the
adapter (the AC adapter has priority).
12. 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.
