| Secondary calibration | Calibration 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 protection | Setting operation can be locked to prevent unauthorized modifications of default values and calibration by malfunction |

| I/O section | |
| External output signal | Transistor’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 signal | ON 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. |
