4) Press the key ( ) to be set to 100% and the current output will
be 20mA Press the key ( ) to be set to 0% and the current
output will be 4mA.
5) Repress the key (100%/START) so as to exit the step current
output.
Auto-ramp Output
v
1) Connect as shown in Figure5-1;
2) When the key (OUTPUT) is pressed the OUTPUT appears in
the LCD, it denotes the Instrument is in an output state;
3) When the key (STEP/AUTO) is pressed, the symbols ‘OUTPUT’
OFF’ ‘ S’ along with ‘4mA’ appear in the LCD. If so,it denotes that
the Instrument is getting into the mode of RAMP;
4) Repress the key (25%/RAMP) again so as to change the type of
the output ramp, which finds itself in the lower left of the LCD.
The type appears with ‘ s’ ‘ ’ ‘
F
’. in proper order. These
symbols denote a low speed ramp and a high speed ramp
respectively. The former is set to a cycle up to 60S and the latter is
up to 30S, while the auto-stair step ramp pauses 5 seconds at
each step;
5) Press the key (100%/START) to start the output of the set
waveform when the symbol ‘ON’ appears, Now repress the key
(100%/START) again and the output will pause on a current value
and the symbol ‘OFF’ will appear. Then press the same key again
and output will continue to do the set steps from the pause value.
When the symbol ‘OFF’ appears, press any one of the keys ( ) ,
( ) , ( ) , ( ) so as to bring the output back to the 0% Then the
value of 4mA appears in the display.

Simulating Transmitter Output (XMT)
1) Insert one end of the test lead to the ‘XMT’ output jack of the
Instrument and connect the other end with the input terminal of
the user’s device as shown in the Figure 5-2;
2) The key-operation is the same as that of the current output.
Note
•
Range of power supply 5 to 25VDC.
•
Usage : during the operation of the current output, use the
external 24VDC power supply in a mode of connecting
a transmitter, thus being able to prolong the working life
of the battery.
