The FI-521 is a bi-directional load cell instrument accepting both positive and negative load cell signals, internally performing the analog to digital conversion at 80 times per second. The FI-521 Indicator features an IP65 stainless steel enclosure for reliable performance in wet or dusty environments. Included swivel mounting bracket allows for wall or bench mounting. Watertight connections include the AC power cable, 7-pin load cell quick disconnect cable connector and three additional cable ports. The instrument's 6 key front panel enables all setup, configuration and calibration procedures. FI-521's calibration procedures include a multi-point calibration feature for correcting the performance of non-linear load cells. The indicator has memory to store calibration information for up to three load cells. The FI-521 can store peak and first peak values at 80 Hz. Operators can track stored data using date/time information and a 6-digit ID number. The stored data can then be printed or sent to a PC or other device using programmable print and data output formats. The FI-521's four logic level inputs and the bi-directional serial port can receive control commands from external devices. The instrument can control external devices via any of the two standard cutoff outputs. Also, has on board an analog output that is fully calibrated for 0 to 2.5 VDC.
