Important Notice ---- Warning
Check the position of the “Measurement/Calibration Switch”
on the rear panel before turning on the device. Please refer
to Figure 2. The switch must be at the measurement (left)
position. Loss of calibration data will occur if the switch is at
the calibration (CAL) position when the instrument is used
in measurement application.
The instrument is calibrated before shipment. Only qualified
calibration agencies with proper standard resistors should
perform the calibrations of this device. Please refer to

1 Introduction
The AM8060 precision thermometer is a dual-channel PRT readout. It
can be used either as a temperature measurement device or a
temperature reference standard. It is capable of working together with
various types of platinum resistance thermometers (PRTs) and can
measure temperatures from two probes simultaneously. The measured
temperature is calculated by the embedded microcontroller by
following ITS-90 standard. The device has a strong data acquisitions
capability by using a wireless module (optional), an USB connection
to PC or a flash drive interface that can do ‘plug-and-record’. With
these flexible peripherals, temperature data can be easily captured and
saved in real time.
1.1 Main Application
Temperature measurement with standard platinum resistance
thermometers (SPRTs), secondary platinum resistance
thermometers (Secondary PRTs) and precision industrial
platinum resistance thermometers (IPRTs).
PRT calibrations or comparisons.
Temperature reference for dry-wells or temperature baths.
1.2 Main Features
High accuracy: 0.008 ºC at 0 ºC
High resolution，0.001 ºC
Concurrent two PRTs measurements and data capturing.
Display of two PRTs temperature in Celsius ºC，ºF, resistance
Ωand temperature difference.
2.7”OLED display.
Touchpad for function control.
Flexible probe/sensor parameter adjustments and settings.
USB interface for transmitting and saving real time temperature
data.

4 General Operations
The AM8060 precision thermometer is a dual-channel temperature
readout. It can measure temperature of two probes concurrently. It can
also be used with just one probe for single channel temperature
measurement.
4.1 Connecting the probes
The AM8060 can work with one or two probes for temperature
measurement. Figure 3 shows the rear panel of the AM8060.
Probe 1 can be connected to terminals marked with S1, and Probe
2 to S2.
Figure 3: Rear Panel and Probe Terminals
4.2 Instrument connection with AC power
AM8060 operation requires power of AC100V~240V.
4.3 Instrument front panel display and touchpad
After the power is turned on and the probes are connected, the
device should show initialization information, including the
instrument interface status, measured temperatures of the
Set to CAL when doing
Calibration.

probe/probes and temperature difference. This information is
shown in 4 lines, as seen below:
Line 1 is the instrument interface status, including USB flash drive,
wireless communication status and USB to computer interface
status. If the “Udr”is shown in Line 1, a USB flash drive is
connected to the USB host interface; if “ZB-xx (where “xx” are
numbers) displays on Line 1 as shown above, it means the Zigbee
wireless data capturing is working; if the display shows“USB”on
Line 1, then AM8060 is connected via its USB client interface.
Line 2, which is indicated with ‘t1’, shows the measured
temperature of Probe 1 (S1). The“SPRT”at the end of the Line 2
tells the type of probe of Probe 1 (S1). The AM8060 supports two
types of probes. “SPRT” indicates a 25Ωor 100 Ωstandard
platinum resistance thermometers. “IPRT” indicates a 100Ω
industrial platinum resistance thermometer. The “C” shown at the
end of Line 2 indicates that the temperature is in Celsius.
Line 3, which is indicated with ‘t2’, shows the measured
temperature of Probe 2 (S2).
A “>” will toggle in front of “t1”or ”t2”to indicate which probe is
being measured. Each toggling instance is one measurement.

4.5 Selecting Sensors/Probes and Adjusting Parameters
4.5.1 Probe Types
AM8060 can work with different types of PRTs. Users can
choose probe types and input the parameters of the probes.
The menu key
MENU
and return/right shift key can be used for
probe selections and parameter adjustments.
The probes compatible with AM8060 are:
25 Ωor 100 ΩSPRTs, or
25 Ωor 100 ΩSecondary PRTs, or
100 ΩIPRTs.
The temperature coefficient of these probes can either be
0.00385 Ω/Ω/°C or 0.003925 Ω/Ω/°C.
The probe types working with AM8060 are classified and
displayed as IPRT and SPRT：
If the probe is an industrial or precision platinum resistance
thermometer probe with a temperature coefficient of 0.00385
Ω/Ω/°C, AM8060 will categorize the probe as “IPRT”.
AM8060 calculates temperature according to CVD (IEC751)
equation.
