Digital Manometer with record function LEO Record is an autonomous battery powered instrument with digital display designed to record pressure and temperature over long periods. Both the piezoresistive LEO Record as well as the capacitive LEO Record (ideal for low pressure ranges) offer the following advantages: - High measuring accuracy, resolution and robustness - High data security due to the use of a non-volatile memory - Display of the actual pressure and the record status - Recording of the pressure and temperature - Simple and well structured configuration- and read-out software (Logger 4.x) for PC or PDA - Combination of event-controlled recording and interval recording prevents unnecessary data being recorded (i.e. only measuring the pressure changes...) - Installation data (and comments) of the measuring station can be stored in the instrument - Pressure connection with G1/4” thread (other threads on demand) The pressure is measured and displayed once per second (shortest interval). The top display LEO Record indicates the actual pressure, the bottom display shows the record status. All LEO Record versions have 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 instruments have the following functions: Zero The ZERO-function allows to set any value as a new Zero reference. All standard instruments are calibrated in bar. The pressure can be indicated in the following units: bar, mbar/hPa, kPa, MPa, PSI, kp/cm2, (m)H2O RECORD The record can be started or ended with the operating keys. The configuration of the record takes place via interface/software.

Functions, ranges and accuracy are identical to the standard LEO Record version. Specifications LEO Record (Ei) capacitive Standard FS Pressure Ranges1 2 PR (relative) / PD (differential) Overpressure Negative Overpressure Total Error Band (10…40 °C) mbar mbar mbar FS ≤ 100 mbar: ± 0,1 mbar The factory setting of the zero for the ranges ≤ 61 bar absolute is at vacuum (0 bar absolute). For relative pressure measurements, activate “ZERO SEt” at ambient pressure. Instruments > 61 bar absolute or instruments with a relative pressure sensor (label marked with: Range: rel) are calibrated with the zero at atmospheric pressure. Other pressure ranges as well as instruments with relative pressure measuring cells on request For the PD-version, a tube connection Ø 6 mm for the reference is available
