5 Instrument Calibration And Accuracy
Adjustments
AM8060 is designed for temperature measurement by measuring
the probe resistance and converting it into a temperature.
Consequently, the resistance measurement is very critical, and the
instrument must be calibrated correctly. Every AM8060 is
calibrated before shipment.
AM8060 needs regular calibration performed by qualified
professionals. One year calibration interval is recommended.
Users can calibrate AM8060 using standard resistors with
calibrated values.
Warning: It is required to set correct R0 (Rtpw) values in Sensor 1
(S1) before calibrations. To calibrate AM8060 in the range from
10 Ω to 50 Ω, R0 (Rtpw) needs to be set to 25 Ω. To calibrate
AM8060 in the range from 50 Ω to 375 Ω R0 (Rtpw) needs to be
set to 100 Ω.
In case of AM8060 out of tolerance, its accuracy can be adjusted.
Only qualified agencies, labs or institutes (who must be equipped
with calibrated 25 Ω and 100 Ω standard resistors) should adjust
the accuracy of AM8060.
The calibration should be done in an environment with room
temperature of 22±2°C.
Instrument calibration procedure: (No special sequence
for 100 Ω and 25 Ω calibration)

for Data
Acquisition
The flash drive recording start/stop key
REC
can be used for
saving data to the USB flash drive.
There is a USB port on the rear panel of the AM8060 which
can be used to store the measured temperature data to a flash
drive. Any flash drive with size lower than 4 gigabytes can
be connected to the “UDrive” connector at the rear panel.
The following steps explain how to transfer data from the
AM8060 to a flash drive:
1) Connect a flash drive to the “UDrive” USB port at the
rear panel of the AM8060.
2) When the flash drive is connected, the display will say
“Device Detected” “D:/p” to indicate that the flash
drive is detected. The top left hand corner of the display
should display “UDr” to remind users that a flash drive
is connected and is available for data capturing.
3) If the flash drive is connected while the AM8060 is
turned off, AM8060 will display “Device Detected P2”
during initialization to indicate that the flash drive is
detected, and the upper left hand corner of the display
will show “UDr” to remind users that a flash drive is
connected and available for data capturing.
4) To save the temperature data measured by the AM8060
to the flash drive, just press the
REC
key on the front
panel. AM8060 will emit a short beep and the LED

User’s Guide
31/43
above the
REC
key will be turned on. This is to inform
the user that the temperature data is being written to the
flash drive. The saved file name is U2DATA.txt.
5) If users want to stop the data saving, just press
REC
key
on the front panel. AM8060 will produce a short beep
and the LED above
REC
key will be turned off to
indicate the process has been halted.
The following list is an example of data saved in the
U2DATA.txt file on a flash drive. Time column
indicates time in unit of seconds; t1, t2 and t1-t2
indicate temperature readings from sensor 1, sensor2
and difference of two sensors in Celsius. An “end” is
written to the file when
REC
key has been turned off.
Time t1 t2 t1-t2
0.23 -4.525 +529.475 -534.000
1.44 -4.524 +529.475 -534.000
2.64 -4.524 +529.475 -533.999
3.85 -4.524 +529.475 -533.999
5.05 -4.524 +529.475 -534.000
6.26 -4.524 +529.475 -534.000
7.46 -4.524 +529.476 -534.000
8.67 -4.524 +529.476 -534.000
end
6) The above operations can be repeated to do multiple
time data saving.
7) The temperature data file U2DATA.txt in the flash
drive can be transferred to a computer. Just unplug the
flash drive when it is stopped (when the LED above the
REC
key is off）and plug it into a computer’s USB
connector. Once the flash drive is detected by the
computer’s OS, users can copy the file over normally.

While using the flash drive, the data saving period can be adjusted
with the front panel. The default saving period is 1.21 seconds，
and it can be set as a multiple of this value, with the multiple
ranging between 1 and 65,535. The instructions for this are as
follows:
A. When AM8060 is in a normal working state, press
MENU
key
and then hold key for 3 seconds. The AM8060 will
display the main menu as below:
B. Press key or key to move the cursor line with ”>”
sign to “ > U-Drive Setting”, then press key to go to the
“Record Cycle adjustment” program, as seen below. “N”
represents how often the temperature will be saved as a
multiple of 1.21 seconds. The current value is “1”.
C. To set a sample frequency other than “1”, press and hold
key while pressing key, and a display similar to the one
below will appear.

It should be noted that this operation is a two-key
operation. Don’t release the key before touching
key.
D. Press key or key to adjust the “N” value (which must
be equal or greater than 1).
E. After the adjustment, press
MENU
key. The new adjusted value
will blink to indicate whether the user wishes to save this
new N value. For example，the above picture shows the new
N value as 9, which means the AM8060 will save data to the
file every 9x1.21 seconds. To save this value, press and hold
key and then press key. If users DON’T want to save,
just press
MENU
key to exit.
Note: saving the N value is a two-key operation：do
not release key before pressing key.
Otherwise the new value will not be saved.

multiple times until the
AM8060 returns to its normal working state.
Note: The parameter adjustments should only be performed
while the flash drive is not in the data saving process.
