3.4 Power up
3.4.1 Power on/off
The power switch is tact switch with indicator light.
Press the power key for at least 2 seconds, release the power key after the buzzer beeps,
instrument will power up and power switch indicator will be turned on.
After the instrument is powered on, it will load Applent ATOS operating system, and this
process will take 10 seconds.
Then ATOS operating system will begin to perform AT4610/AT4710 procedure.
TIP
When instrument is in process of start or instrument’s procedure collapse or crash, press power switch or
about 4 seconds, then power will be forced to turn off.
3.4.2 Instrument Version
Figure 3-4 Instrument’s version
After finish loading ATOS operating system, the screen will display product model for a while
and its version.
In addition, on <SYSTEM CONFIG> page and <SETUP> page, instrument’s version is also
available.
You can also check instrument version by remote control’s command [idn?]
3.5 How to Connect
The input terminal on rear panel:
Figure 3-5 Test input terminal on rear panel
There are 10 groups of input, each input will AUTO configure 2 terminal, 3 terminal or 4
terminal according to input type.
Measuring voltage and thermocouple use 2 terminal, RTD uses 3 terminal or 4 terminal, and
resistance use 4 terminal.

3.5.1 Connection of Voltage
Figure 3-6 Connection of voltage
Please connect voltage source’s positive pole to input terminal’s positive pole, connect negative
pole to input terminal’s negative pole, as per the above figure, otherwise, instrument will
display negative value.
WARNING
The test terminal is limited to connect to DC voltage, connect to AC voltage will damage instrument.
Input voltage cannot exceed 120VDC.
3.5.2 Connection of Thermocouple
Instrument supports 8 types of thermocouple, connecting method for each type of thermocouple
is the same.
Figure 3-7 Connection of thermocouple
Please plug 2 terminals of thermocouple to positive and negative test terminal, generally
speaking, red wires is positive pole, black wire is negative pole.
WARNING
Instrument allows thermocouple to work with alive test, but ensure that the live voltage does not exceed
300VDC.
The MAX allowed voltage between input terminals is 300VDC.
If exceeding the above voltage, the input circuit of instrument will be damaged.
3.5.3 Connection of 3-wire RTD
Figure 3-8 Connection of 3-wire RTD

AT4610/AT4710 User’s Guide
In order to eliminate the effect of lead resistance, RTD usually use 3-wire to connect, please do
it as per the above figure.
3.5.4 Connection of Resistance and 4-wire RTD
Figure 3-9 Connection of resistance and 4-wire RTD
4 terminal method can efficiently eliminate the error caused by lead resistance.
AT4610/AT4710 can only use 4-wire to measure resistance, high precise RTD also use 4-wire
method to connect.
TIP
The instrument uses 4-wire connecting method to measure resistors.
