User manual - WEIGHT METER SWI-94
- Do not use the unit in areas where there is risk of explosions.
- Do not use the unit in areas with significant temperature variations, exposure to
condensation or ice.
- Do not use the unit in areas exposed to direct sunlight.
- Make sure that the ambient temperature (e.g. inside the control box) does not
exceed the recommended values. In such cases forced cooling of the unit must
be considered (e.g. by using a ventilator).
The unit is designed for operation in an industrial environment and must
not be used in a household environment or similar.
2. GENERAL CHARACTERISTICS
Weight meter
SWI-94
is designed for cooperation with load cells (strain gages) in
application not required to be approved. Device is equipped with push-buttons allow easy
setting of tare and zero, and also switching between nett and gross indications. Measured
weight is displayed on 6-digit readable LED display. The device can be equipped with two
relay outputs or two OC-type outputs and one of following: active current output, passive
isolated current output, active voltage output, which allow to use as controller for simple
systems with batching function. Build in analogue output and RS-485 interface enable remote
controlling of the device by a host system if required. The device software allows to use two
calibration methods: data sheet calibration, or dead weight calibration. All critical states of the
device are signalised by proper error messages.
