Intended use
The device measures the absolute pressure in the air, clean water or in non- corrosive/non-ionizing gases. A direct measurement of the environmental pressure can take place or the measurement pressure is taken with a suitable hose connected to the port. Relative meas-urements can also be conducted with the integrated special function NVLL.

Applications include:

ECO 240-1| ECO 240-2
Barometric measurements (e.g. weather)| Barometric measurements (e.g. weather)
Vacuum measurements (down to 0.0 hPa abs., negative pressure via hose or even with complete device evacuation)| Vacuum measurements (down to 0 hPa abs., negative pressure via hose or even with complete device evacuation)
| Pneumatic measurements (up to 14000 hPa abs. or 14 bar abs.)

The pressure connection is made at the supplied interchangeable pressure connection ports with suitable hoses – 4 different connection options are available as standard, many other connection options can be used easily and reliable with G 1/8 adapters.

The device must only be used under the conditions and for the purposes for which it was de-signed.

It must be handled with care and used according to the technical data (do not throw, strike, etc.). Suitable measures must be used to protect the pressure connections and be protected from dirt.

Note
Complete evacuation see Vacuum measurements at page 13.

Qualified personnel
For commissioning, operation and maintenance, the relevant personnel must have adequate knowledge of the measuring process and the significance of the measurements. The instructions in this document must be understood, observed and followed.

In order to avoid any risks arising from interpretation of the measurements in the concrete application, the user must have additional expertise. The user is solely liable for dam-ages/danger resulting from misinterpretation due to inadequate expertise.

Open the adjustment menu
The sensor adjustment can be adjusted with the zero point correction and the gradient cor-rection. If an adjustment is made, you change the pre-adjusted factory settings. This is signaled with the display text PR.OF or PR.SL when switching on.

1. Switch the device off.
2. Hold the down button and press the On/Off button to switch on the device and open the  Adjustment menu.
3. The display shows the first parameter. Release the down button.

Formula

• Zero point correction: Displayed value = measured value – PR.OF
• Gradient correction: Display = (measured value – PR.OF) * (1 + PR.SL / 100)

Measurement Basics

Vacuum measurements
The device is especially suitable to measure rough vacuum via the pressure port very fast. But if the complete device is evacuated the following has to be considered

Caution Damage possible by fast complete evacuation!

Due to the water tight construction a complete evacuation of the device may de-grade water protection. The keypad/display screen may break loose. If the device should still be used for this application, the following options are available

• Remove the o-ring of the battery compartment! The Instrument then is no more water protected! Changing battery.
• Specialized variants ECO 240-1-VAC!

Special functions
With the special functions that can be selected via the Configuration menu, the device can be optimized for special measuring tasks. After it is switched on, the device starts up in standard measuring mode, the relevant special function is started by pressing and holding the Function key for 4 s.

NVLL Tare function
The special function FVNC NVLL has been selected in the configuration menu.
The display can be zeroed by pressing the Function key for 4 s. If the tare function is activated, NVLL blinks in the lower display. The tare function can be reset by pressing the Function key again for 4 s.

Note
The tare function is independent of the zero point correction accessible via the adjustment menu.

AVR 0: 02 / AVR 0:05 / AVR 0: 10
Fast measurement with mean value over 2 s / 5 s / 10 s

• Mean value mode for measurement of heavily fluctuating pressures.
• In the Configuration mode, a special function AVR 0:02, AVR 0:05 or AVR 0: 10 has been selected.
• By pressing and holding the Function key for 4 s the measurement with mean value can be activated.
• The different mean value times of 2, 5 or 10 seconds can be selected depending on the requirement.
• The first parameter is shown in the auxiliary display.

By pressing and holding the Function key for 2 s the special function can be deactivated. END FVNC appears in the display.

If the tare function is active when calling up the special function AVR, it can be reset by pressing the function key for 4 seconds. In order to reactivate tare, the special function must be changed in the configuration menu.

Pressure Connection

Note
Suitable hoses must be used for vacuum measurements, silicon is suitable as a hose material due to the low rigidity!

Caution Air pressure at port variant UT!
With higher pressures greater than 1 bar, the hoses must be secured to prevent unintended loosening. Suitable GDZ hose clamps are used for this purpose.

• 6×1 mm PVC (GDZ-01) up to 5 bar rel., vacuum-suitable!
• 6×1 mm PE (GDZ-02) up to 10 bar rel., vacuum-suitable!
• 6×1 mm PUR (GDZ-03) up to 9 bar rel., vacuum-suitable!

Replacement of pressure hoses
The pressure connections are screwed into the product with a standard G 1/8 inch thread with end seal. All common pressure connections with this design can be connected.

Note
Use a suitable tool for tightening and observe the maximum torque of 2 Nm!

Supplied connection :

Operation and maintenance

Operating and maintenance notices

Note
Pressure connections must be protected from soiling.

Battery

Battery indicator

• If the empty frame in the battery display blinks, the batteries are depleted and must be replaced. However, the device will still operate for a certain length of time.
  

• If the BAT display text appears in the main display, the battery voltage is no longer adequate for operation of the device. The battery is fully depleted.

Changing battery

Danger Danger of explosion!
Using damaged or unsuitable batteries can generate heat, which can cause the batteries to crack and possibly explode!
Only use high-quality and suitable alkaline batteries!

Caution Damage!
If the batteries have different charge levels, leaks and thus damage to the device can occur.

• Only use high-quality and suitable alkaline batteries!
• Do not use different types of batteries!
• Remove depleted batteries immediately and dispose of them at a suitable collection point.

Note

• Unnecessary unscrewing endangers the protection against moisture and should therefore be avoided.
• Read the following handling instructions before replacing batteries and follow them step by step.
• If disregarded, the device could be damaged or the protection from moisture could be diminished.

1. Unscrews the Phillips screws (A)and remove the cover.

2. Carefully replace the two Mignon AA batteries (B).
   Ensure that the polarity is correct! It must be possible to insert the batteries in the correct position without using force.

3. The O-ring (C) must be undamaged, clean and positioned at the intended depth.

4. Fit the cover (D) on evenly. The O-ring must remain at the intended depth!

5. Tighten the Phillips screws (A).

Disposal
Separation by material and recycling of device components and packaging must take place at the time of disposal. The valid regional statutory regulations and directives applicable at the time must be observed.

Note

The device must not be disposed of with household waste. Return it to us, freight prepaid. We will then arrange for the proper and environmentally- friendly  disposal.

Private end users in Germany have the possibility of dropping off the device at the municipal collection center. Batteries must be removed beforehand!
Please dispose of empty batteries at the collection points intended for this purpose.
