Input of approx. 0.5mV/V or 1.0mV/V, Selectable adjust to zero [by dip switch on the rear panel]
Gain adjustment range2 stages of gain selectable according to the output of loadcell [by dip switch on the rear panel]
0.5 - 1.5mV/V for HI gain, 1.0 - 3.0mV/V for LO gain (digital adjustment)

Secondary calibrationCalibration can be carried out without an actual load by connecting a resistor to one of the bridges of a loadcell.
 
SETTING SECTION
Setting method・ Keyboard operation (membrane switch with a key click buzzer) 
・ External setting is available by installing a setting point option or RS-232C option
Setting value storage・ Initial set values: NOV RAM (Non-volatile RAM)
・ Other set values: C-MOS RAM with backup of a lithium battery (Effective for more than 7 years depending on usage conditions and storage environment.)
Setting value protectionSetting operation can be locked to prevent unauthorized modifications of default values and calibration by malfunction
 
INPUT/OUTPUT SECTION
External output signalTransistor’s open collector output (Emitter = COM terminal); Output is LO when transistor is ON (Near zero, SP1, SP2, SP3, go or comp, over, under, high limit, Low limit, stable, weight alarm or error, run)
External input signalON when shorted to COM terminal by TTL-level relay, switch, transistor, or open collector output. (Feed / discharge, tare ON, tare OFF, zero, gross / net, hold or judgment, start, stop) (Drive current: 10mA or less)
Output Conditions- SP1: Net weight >= final weight-SP1
- SP2: Net weight >= final weight-before final
- SP3: Net weight >= final weight-FF
- Under: Net weight < final weight-underweight
- Over: Net weight > final weight-overweight
- Go: Final weight+overweight >= netweight >= final weight-underweight
Interface
  • ・ SIF:
  • 2-wire type serial interface (standard); Interface to link with Unipulse printer or external display
  •  
  • ・ SPI:
  • Interface for set-point units (Optional); Interface to enter various set values via digital switches
  •  
  • ・ BCO:
  • BCD parallel data output interface (Optional): Parallel interface to transmit weight data to a printer, external display, PC or sequencer.
  •  
  • ・ 232:
  • RS-232C communication interface (Optional): Write (change) / read weight data, various statuses and setting values from a PC or sequencer.
  •  
  • ・ 485:
  • RS-485 communication interface (Optional): Allows longer-distance communication than RS-232C. ID numbers are set, and multiple units of F701 are parallel-connectable.
  •  
  • ・ DAC:
  • D/A converter interface (Optional); Interface to convert weight data to current signal and output it.
