fine potentiometers on the left. High alarm limits are set
by the two coarse and fine potentiometers on the right.

digits and the adjustment potentiometers) from the normal position
to either the SET HI or the SET LO position. See drawing on page

coarse

potentiometer until the display reads

the value of the alarm limit. Make any final adjustments with the

Install the front panel lens.

Ensure that power is

disconnected before reconnecting signal wires.
