CONTROLS

Digital Manometer with peak recording/peak Measuring rate: 5 khz
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: The ZERO-function allows to set any value as a new Zero reference.
Barometric pressure variations can thus be compensated.
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 > 30 bar are calibrated with ambient pressure as a Zero
reference.
Cont: The instrument turns off 15 Min. after the last key function.
Activating CONT(Continuous) deactivates this automatic turn-off.
Units: All standard instruments are calibrated in bar.
The pressure can be indicated in the following units: bar, mbar/hPa, kPa, MPa, PSI, kp/cm2

Optional accesories
- Protective rubber covering (not for Ei-version)
- Carrying bag
