Set to HLFS
Raise level to desired alarm point (1" minimum probe
covered). Turn setpoint adjustment counterclockwise until
red LED turns on. Set failsafe as required.
All Other Sensing Elements
All Z-tron IV controls are factory set to switch in conductive
materials [setpoint adjustment is set to full clockwise (CW)
position]. No calibration adjustment is necessary.
If this instrument had been previously adjusted for use in
a insulating materials, and is now intended for use in a
conducting material, use a small screwdriver to turn the
setpoint adjustment to the full clockwise (CW) position. No
other adjustment is necessary.
