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 '
'、 ' ' 、 '
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 the 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.
• 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.
