Fine mA adjustment
When choosing the Fine adjustment option, the screen will appear which shows the active mA output
value. Change this number to any desired value between 2mA and 20mA and when
ENT button is
pressed, the RT-30EX will output this value. This also returns the screen to the adjustment type screen.
Press
SEL to see output value again and make new change.
Coarse mA adjustment
When choosing the Coarse adjustment option, the screen will appear where the mA output value can be
changed. When pressing the
UP button, the screen value (and mA output value) increments by 1mA, to
a max of 20mA. When pressing the DN button, the screen value (and mA output value) decrements by
1mA to a min of 2mA. This is the fastest way to test the mA output range if no specific mA output value
is required. Press the
EXIT button to leave this mode.
Limit & frequency adjustment
The Limit and Frequency outputs can be manually controlled to change states simultaneously using one
of 3 methods. The fine adjustment allows the user to enter a specific frequency to output between 2Hz
to 4,500Hz. The coarse adjustment allows the user to output a frequency and change the rate in 25Hz
increments using the
UP and DN buttons. The ON/OFF adjustment allows the user individually toggle
the output state between on and off using the UP , DN and SEL buttons.
