display. There are four function keys that are defined as followings：
MENU : MENU KEY,
: INCREMENT KEY,
: DECREMENT KEY, and
: RIGHT SHIFT and RETURN KEY.
The top panel of AM8010 is shown in Figure 3-2. There are three
interfaces: “SENSOR，“USB or EXT POWER” and power
switch “OFF/ON”.
Figure 3-2: AM8010 Top Panel
A foldable tilt foot support is mounted on the back of AM8010. It
helps user to put the meter in a stable position with a display angle.
There is a battery cover on the back side of AM8010 Precision
Thermometer. Two AAA size batteries are used to power the meter.
A sliding switch besides the battery holder can be seen when the
battery cover is opened. This switch is used for calibration only.
Warning: Inappropriate setting change to this switch can cause loss
of calibration data. Instructions of using this switch are shown in
4.1.

AM8010 Precision Thermometer User’s Guide

4 General Operation
4.1 Mode Switch Setting
There are two operating modes of AM8010: Measurement Mode
and Calibration Mode. Users can switch the mode by using a Mode
Switch. The Mode Switch is located near the battery holder. The
default mode is set to Measurement Mode.
Note: Only trained calibration personnel can set the switch to
“Calibration Mode”. See detailed instructions of calibration
procedure in Chapter 7.
The procedures to set this switch are as followings:
1. Turn off AM8010.
2. Open the battery cover at the back side of AM8010. Mode
Switch, which is a sliding switch, is located besides the
battery holder.
3. Text “MEA” and “ADJ” indicate whether AM8010 is set to
“Measurement Mode” or “Calibration Mode”.
4.2 Battery Installation
AM8010 works with dual power supplies: battery and USB. When
AM8010 is powered by USB, the batteries are not used.
To install the batteries, open the battery cover at the back of
AM8010, follow the polarity signs on the battery holders.
AM8010 works with any type of AAA size batteries, alkaline or
rechargeable batteries.
Caution: Do NOT combine different kind of batteries together.
Make sure the power switch is at “OFF” position during battery
installation.

4.3 Power with External Adapter and USB
An AC/DC adapter (AC 100V ~ 240V input, DC5V output) can be
used to power AM8010.
The advantage of using the adapter is that the backlight of the LCD
display will be turned on and it is suitable for dim light conditions.
The connection procedures of the AC/DC adapter are as follows:
1. Connect USB A side to the adapter USB socket.
2. Connect USB mini-B side to “USB” connector of AM8010.
3. Plug the adapter to AC 100V ~ 240V power point. Switch on
the AC power.
4. If AM8010 is not powered on, switch it on. If AM8010 is
already powered by batteries and the power switch is on, the
backlight of LCD should illuminate.
5. The USB cable can be unplugged anytime. If AM8010 is
powered by batteries, functionality will continue.
AM8010 can be connected to a computer with the USB interface. In
this case the computer is the power source for AM8010.
4.4 Sensor Connection
PRT Sensors can be connected to the AM8010 “SENSOR” socket
with a 5-pin connector that is provided in this package. Connecting
steps are as follows:
1. Align the notch of sensor plug to the notch of “SENSOR”
socket.
2. Push in the sensor plug. At this moment, do not turn the knob.
Turning the sensor connector can cause damage of the socket
and plug.
3. After the plug is fully pushed in, turn the locking ring of the
plug clock-wise until it is fully tightened.

AM8010 Precision Thermometer User’s Guide
Rev. 201609V3 8/30
4. To remove the sensor, just do the reverse of the above
procedure: turn the plug locking ring counter clock-wise, until
it is free, then pull out the plug.
4.5 Power On/Off Control
The power switch is on the top panel of AM8010. It is marked with
“OFF/ON” text. Users can follow the sign to turn the meter on/off.
4.6 Display of Measurement Results
The temperature measurement results are displayed on the LCD
screen. There are four lines of information as shown in Figure 3-1.
The main information is temperature in Celsius (C), Fahrenheit (F)
and sensor resistance (OHM). The other information includes
sensor type, USB connection status, battery low status and no
sensor indications.
The first line is the status information line. The second, third and
fourth line shows the measured data, which are temperature or
sensor resistance.
As shown Figure 3-1, the top line is the status information line. The
information includes：
1. Status sign. It is a flashing dot at the upper left corner. It
should flash under normal conditions.
2. Main measurement parameter. It is located just to the right of
the status sign. It should be either “t =” or “Rt =” which
means the second line information is temperature (“t=”) or
sensor resistance (“Rt=”). The information of the second line
can be changed by users. The details are shown in “4.7
Touchpad Operation”.
3. USB status. When AM8010 is connected to a computer’s
USB interface，“USB” will show up near the center of the
first line.
4. Sensor type. Two types of sensor, “IPRT” or “PRT”, are
supported by AM8010. They are displayed as “IPRT” or
“PRT” on the LCD near the end of the first line. Users can

AM8010 Precision Thermometer User’s Guide
Rev. 201609V3 9/30
configure the sensor type by following the procedures that are
detailed in Chapter 6 “Sensor Parameter Input/Adjustment”.
“IPRT” is defined as a 100 Ω sensor with temperature
coefficient α=0.00385. “PRT” is defined as a 100 Ω
SPRT/PRT with temperature coefficient α=0.003925
(WGa≥1.11807).
5. “NO SENSOR” status. “NO SENSOR” will be displayed
when no sensor is connected to AM8010.
6. “LOW BAT” status. “LOW BAT” is displayed when the
batteries are low in power.
The second line shows the measured results with larger fonts to
help users to focus on the key readings. The information of second,
third and fourth line can be scrolled up or down based on the user’s
preference.
4.7 Touchpad Operation
There are four touch keys on AM8010 front panel. These touch
keys are used for scrolling up/down measurement data, or for
sensor parameter adjustment and calibrations.
Note: These keys are not mechanical push buttons. They are
only sensitive to finger touch.
When the meter is set to Measurement Mode, and are
to select the measured readings in Celsius (C), Fahrenheit (F)
or sensor resistance (OHM).
MENU and keys can be used for sensor type selection and sensor
parameter adjustment. These two keys are also used in
Calibration Mode (see Chapter 6).

6 Sensor Parameters Input/Adjustment
AM8010 supports two types of sensors: IPRT and PRT。
IPPT: high precision 100 ohm Platinum Resistance Thermometer or
Industrial 100 ohm Platinum Resistance Thermometer with
temperature coefficient of α=0.00385. The temperature is
calculated based on CVD formula. Users can input/adjust following
parameters of an IPRT: R0, A, B and C.
PRT: high precision 100 ohm Platinum Resistance Thermometer or
100 ohm standard Platinum Resistance Thermometer (SPRT) with
temperature coefficient of α=0.003925 (WGa≥1.11807). The
temperature is calculated based ITS-90 formula. Users can
input/adjust the following parameters:
 Rtp: the sensor’s triple point of water.
 a4, b4: ow temperature range parameters.
 a, b, c: high temperature range parameters ( for some type of
sensors, b and c may equal to 0. Refer to ITS-90 for details).
After users input/adjust the correct parameters the sensor type is
displayed on the LCD of AM8010 and the parameters are used in
the calculation.
Note: Users need to set the parameters corresponding to the sensor
to get the optimal measurement. These parameters can be obtained
from qualified calibration institutes.
The detailed procedure to set the sensor type and parameters are as
follows:
1. Power off AM8010. Install batteries in the AM8010, or
connect AM8010 to a power adapter or a running computer
USB interface. Make sure each battery has enough power. It is
suggested to use new batteries for parameter setting or
calibration.
2. Set the Mode Switch to Measurement Mode. Refer to
4.1Mode Switch Setting.

3. Power on AM8010. If a sensor is connected to AM8010，the
LCD should display the measurement reading. See the
following figure as an example. If no sensor is connected
users can still set parameters of a sensor.
4. Press and hold MENU key for more than 3 seconds，the bottom
right corner of LCD should show “MENU”.
Then hold the MENU key and also press the key at the same
time. AM8010 should enter into adjustment program.
5. The following will be displayed on LCD after step 4. If no
adjustment or setting is needed, press or key to move
the highlight line to“EXIT” and then press key，
AM8010 will go back to measurement mode.
