Weighing technology - calibratability for EWI models

The EWI weighing terminals can be calibrated in compliance with OIML verification class III and IIII. The weighing function is approved for up to 10,000 increments in compliance with OIML R76.
Maximum weighing range from 1 kg to 999,950 kg
Calibration value: e = Max / n
Max. number of calibration values: n = 10,000 for single range and multiple range 3x3000e (however, this depends on ambient conditions and the composition of the modules).
A 24-bit A/D converter with 4 channels and up to 200 conversions/second is used.
The integrated alibi memory (max. 18,000 weighing operations) allows the calibrated transmission of the weight (with date and time) to a printer or PC.

Design

EWI-A - the weighing indicator is housed in a robust aluminium housing with protection class IP 65.
The device is operated via a waterproof keypad with 8 function keys. The large keys have a positive click action and can therefore be used with confidence.
The large 60 mm display with 6 high-contrast digits and status symbols is easy to read, even at larger distances.
LED backlighting ensures good readability in low light conditions. The backlighting can be adjusted via a menu.
The housing is secured using a VESA 75 bracket and is supplied with a table top / wall mount as standard. A stand is available as an optional extra.

Operation

Operation of the device via the membrane keypad is intuitive and easy to learn – even for untrained staff.
Calibration and function setting is easy via the keypad.

Interfaces

The weighing terminal optionally comes with a serial RS-232 interface, which permits bidirectional connection to a scanner/barcode reader, printer, PC or second display. This allows you to print a customer-specific, calibratable document that contains the Alibi number, date and time. One of our signal lamps (traffic lights) can also be controlled via this interface. These can make quality control easier from a visual perspective.

Power supply

The display is powered by a plug-in power supply (100-240V/50-60Hz) as standard.
