【 Mode switch 】
：When the main interface 【 FN 】 is white.Press 【 OUT 】 to switch
the display position of output actual loop current value and engineering quantity
【 Activate independent 24V 】
: After this item is checked, the independent 24V
power supply starts to output from the (24V) port (IN-) port and the (COM) port, and
is not affected by input and output signal type switching
【 Activate Hold 】:
After this item is checked, each time the machine is turned on,
the 24V state will remain in the state of the last turn-on.Otherwise, every time you
turn on the 24V, you need to turn it on manually
【 4.8 】 Ohm Resistance Signal
【 Temperature Unit 】
: Set to Celsius or Fahrenheit
The resistance signal is divided into three types: Pt100, Cu50, and RES.When the
main interface 【 FN 】 is white, press 【 IN/OUT 】 to switch
【 Resistance Offset 】
: Used to correct the resistance value of input/output
�、EXTENSIONS
【 5.1 】 Engineering
When the signal value of analog quantity is used in the industrial field, it is
generally necessary to convert it into engineering quantity value.Therefore, in the
input and output settings of each signal, the instrument can set the upper and
lower limits of its engineering quantity and the upper and lower limits correspond-
ing to the signal value
【 5.2 】 Preset Value
【 Parameter Setting 】
: You can set the signal value corresponding to the up, down,
left and right buttons
【 Operation Instructions 】
: Start and Exit: When the main interface 【 FN 】 is red,
press the up key 【 RCVK 】 to Start/Exit the preset
【 Up, Down, Left And Right Keys 】
: After starting the preset, the backlight of the
up, down, left and right keys will turn green, and the key function will also change
to "output the set value"
【 5.3 】 Signal Conversion
The input signal is converted into an output signal.For example: the input
frequency signal is converted into a current signal, and the input range is 0-1000hz
and converted into 4-20mA
