Keller LEO 1 User Manual

Installation
Screw the G1/4 male port of LEO 1 into the female pressure port and
tighten using the lower hexagon of the trans-
ducer. Loosen the upper hexagon and
rotate the LEO 1 to the desired
position. Retighten.
Battery Change / Battery Life
When the battery starts weakening, a low battery warning (BAT LOW)
will appear in the upper left corner of the display.
Battery change: Open the instrument (turn the display ring beyond
the limit stop). Open the battery compartment and change the battery
(type CR 2430).
The battery life is 180 hours in Peak-mode (at continuous operation)
and 1400 hours in normal measuring mode.
Ranges / Calibration
The factory setting of the Zero for the ranges -1…3 bar or -1…30 bar
is at 0 bar absolute. For sealed gauge pressure measurements,
activate “ZERO SEt” at ambient pressure.
Instruments with the ranges 0…300 bar or 0…1000 bar are calibrated
in a sealed gauge mode with 1 bar absolute pressure as a Zero refe-
rence.
The face of LEO 1 can be rotated through
355°. This feature allows the LEO 1 to be
mounted in all possible positions; vertical,
horizontal or upside down.
