KELLER LEO-Record Digital Manometer User Manual

KELLER LEO-Record Digital Manometer

Description

Digital manometer with record function. The technical data of the digital manometer can be taken from the corresponding data sheet or from the agreed specifications.

Turn-On and Functions

LEO­Record has two operating keys. The left key (SELECT) serves to select the functions and the pressure units. The right key (ENTER) activates the selected function or pressure unit.
Turn­on:
Pressing the SELECT key turns the instrument on. The instrument first displays the full-scale pressure range (top display) and the software version (year/week). The instrument is then ready for use and indicates the actual pressure (top display) and the record status (bottom display). The instrument has the following functions:

• OFF:
  Turns off the instrument and ends an active record.

• MANO:
  Releases the following functions:

  • rEC Strt:
    Starts a record with the ac-tual configuration (set via the software).

  • rEC StoP:
    Ends an active record.

  • ZERO SEt:
    Sets a new pressure zero reference.

  • ZERO rES:
    Sets the pressure zero to factory setting.

Followed by the unit selec­tion: bar, mbar, hPa, kPa, MPa, PSI, kp/cm2, cmH2O, mH2O, inH2O, ftH2O, mmHg, inHg

Example: Setting a new Zero Reference:

• Turn on the instrument by shortly pressing SELECT.
• Wait for the instrument’s measuring mode (≈ 3 s).
• Press the SELECT-key 2 times: MANO appears.
• Press ENTER: rEC Strt appears.
• Press the SELECT-key 2 times: ZERO SET appears.
• Press ENTER: The new Zero reference is set. The instrument returns to the measuring mode.

Notes

1. The functions and units can also be called up by keeping the SELECT-key depressed. Releasing the key enables the displayed function or unit to be activated with the ENTER-key.
2. If the selected function or unit is not activated within 5 seconds with the ENTER- key, LEO-Record returns to the measuring mode without changing any settings.
3. Turning LEO-Record on and off does not influence any of the previous settings.
4. In the measuring mode, the record status is always indicated on the bottom display (run = record is running, PrEP = waiting for start condition, End = recording stopped).
5. If a pressure can not be represented on the display, OFL (overflow) or UFL (underflow) appears on the display.
6. If the actual pressure goes beyond the measuring range, the last valid pressure value starts flashing on the display (overload warning).
7. Temperatures outside of 0…60 °C could impair the readability of the display.
8. Both the PC-Software and the LEO-Record indicate the battery condition in only 2 ways: 0% (BatLow display) and 100%.
9. The internal clock of LEO- Record is also updated when the instrument is turned off. The clock is automatically upated by the PC-software (Logger 5) when writing a record configuration.
10. After a battery change, LEO- Record has to be recon- figured with the PC-Software (Logger 5).
11. If a record is active, the display of the pressure is updated according to the set record interval (at least every 5 seconds).

Installation

The installation must be carried out by qualified personnel only.
Screw the LEO-Record into the female pressure port and tighten using the hexagon of the transducer (pressure connection) (max. torque 50 Nm). The transducer is secured to the housing by a lock nut.
Aligning the face:
Slacken the lock nut at the housing using two open-ended spanners. The display of the LEO-Record can now be rotated in relation to the transducer. Move the face to the desired position and tighten the lock nut.
The LEO-Record’s display can be turned almost 180° to the left and right. The lid of the lower housing can then be opened. ATTENTION: Turning the display more than 180° may damage the wires.

Battery Change / Battery Life

When the battery starts weakening, a low battery warning (BAT LOW) will appear in the display

Battery change: Please turn off the instrument before changing the battery. Open the instrument by turning the display ring be yond the limit stop. Disconnect the battery. Remove weak battery and insert new one (3,6 V Lithium Battery, type SL-760). When reassembling, make sure that the O-ring remains imbedded in the cover. The battery life is up to 5 years, depending on the measuring cycle.

Ranges / Calibration

• The ZERO-function allows to set any pressure value as a zero reference.
• The factory setting of the pressure 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.

Interface (RS485)
The interface converter K-103A (RS232) or K-114A (USB) can be connected at the back of the manometer (Fischer plug Series 103), allowing the data transfer to the PC.
The corresponding PC software can be found on our web site.

General Safety Instructions

• When installing and operating the digital manometer, attention should be paid to the corresponding safety regulations.
• Only mount the digital manometer onto unpressurized systems.
• On pressure ranges ≥ 61 bar, the pressure connections could show residual hydraulic oil, determined by production flow.
• Please also note the corresponding data sheet.
