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.
