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

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.
