DFI 250/250X – DIGITAL WEIGHT INDICATOR
he DFI 250 is powered by Sigma-Delta A/D converter, ensuring
fast and accurate weight readings. It may be configured via the
T
keypad, through the RS232/USB port or through IR-Link with
our PC software. A function key can be configured to select units of
measure (kg, lb, g, & t) hold a weight reading, display an absolute peak
weight, count parts or stabilize a moving mass i.e. livestock. To simplify
operation, Key Disabling allows any or all keys to be disabled. The DFI
250 can be operated using an AC adaptor or four AA batteries that
provide up to 38 hours of continuous operation.
The DFI 250X is IP69K, the highest rated level of washdown protection
in the industry. It hosts all the capabilities of a general purpose indicator,
and features a 6-digit LCD backlit display and a cut-proof, 6-key
