Digital Manometer Keller

General Description

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



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

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 0…300 bar, 0…700 bar or 0…1000 bar are calibrated in a sealed gauge mode with 1 bar absolute 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

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