LEO 1 is a micro-processor controlled, accurate and versatile digital pressure measuring instrument with integrated fast peak-, max.- and min.-function.

The instrument is used in two modes:

Mano-Mode:
The pressure is measured twice per second and displayed. The top display indicates the actual pressure, the bottom display shows the MAX.- or MIN- pressure since the last RESET.

Peak-Mode:
The pressure is measured 5'000 times per second and is brought to the display twice per second. The top display shows the actual pressure, the bottom display the peak- (MAX.) or trough-pressure (MIN.).

LEO 1 has two operating keys. The left key is to turn the instrument on, to select the functions and the pressure units. The right key executes the selected function or unit. The right key is also used to switch between the MAX.- and MIN.-value in both modes.

The instrument has the following functions:

RESET: With the RESET-function, the MAX.- and MIN.-value is set to the actual pressure value.

ZERO: Any value can be set as a new Zero reference. The instruments are calibrated in a sealed gauge mode with 1 bar absolute pressure as a Zero reference. The ZERO allows to compensate for the variation of the barometric pressure or to transfer LEO 1 in an absolute measuring mode by applying a vacuum and executing the zero.

CONT: The instrument turns off 15 Min. after the last key function. Activating CONT (Conti-nuous) deactivates this automatic turn-off.UNITS: All standard instruments are calibrated in bar. The pressure can be indicated in the the following units: bar, mbar / hPa, PSI, kPa, MPa.

Accessories (optional): Protective rubber covering and carrying bag.
