Page 38: Rs-232C Connector
PC connector (25-pin) cross cable The wiring diagram shown above is used for connecting the F805AT-BC to a DTE (data terminal device). Usually a PC functions as a DTE. If you connect it to a DCE (data circuit terminating equipment) such as a modem, use a straight cable.
Page 39: 5．Calibration
5. CALIBRATION 5-1. What is calibration? Calibration represents a set of procedure to verify that the F805AT-BC is correctly adjusted so that it can receive information from the load cell properly. When 100kg of real load is applied to the weighing part (load cell) of a metering device, the indicator connected to the weighing device, if it is properly calibrated, should recognize the data as accurate as possible (e.g.
Page 40: Actual Load Calibration (Weight Calibration)
5.CALIBRATION 5-2. Actual Load Calibration (Weight Calibration) Step by step procedures for actual load calibration are as follows: Toggle the LOCK switch on the rear panel to OFF LOCK(hard) OFF position to enable calibration. Remove software LOCK to enable calibration. LOCK(soft) OFF Select load cell excitation voltage (5 or 10V).
Page 41: Secondary Calibration
5.CALIBRATION 5-3. Secondary Calibration (Calibration using equivalent input) [Weight calibration] Calibration can be carried out using key input, without actual measurement of the load cell’s rated output (mV/V) and rated capacity (e.g. the value you want to display). This method enables calibration without balance weight, and is useful if the instrument is replaced due to failure, or incorrect span calibration is found.
Page 42 5.CALIBRATION Note The value of balance weight should be less than the instruments capacity. If you use rated value written in the load cell’s specification sheet, use the load cell’s rated value for capacity setting. Parallel connection of multiple load cells can, depending on connection scheme, cause small voltage drop due to lead wires.
Page 43: Flow Calibration
5.CALIBRATION 5-4. Flow Calibration Steps for flow calibration are as follows: Toggle the LOCK switch on the rear panel to OFF LOCK(hard) OFF position to enable calibration. Remove software LOCK to enable calibration. LOCK(soft) OFF Select the unit for feed calculation Feed Unit Select decimal place (same setting is used for flow).
Page 44: Preparation For Calibration
5-5. Preparation for Calibration 5-5-1. Releasing the LOCK F805AT-BC provides two types of lock capabilities to prevent unauthorized or accidental alteration of calibration or set data: you can either lock the instrument by front panel operation ([LOCK (soft)]), or by toggling a rear panel switch ([LOCK (hard)]).
Page 45 5.CALIBRATION After calibration has been completed, be sure to lock the instrument again to protect calibration information. Note See "SETTING ITEMS LIST" , on page 177 for the parameters protected by the LOCK function.
Page 46: Weight Calibration
5.CALIBRATION 5-6. Weight Calibration 5-6-1. Zero calibration Zero calibration tunes the instrument’s zero point. Check the weighing device (load cell) and make sure no load is applied to the sensor. A foreign matter placed on the load cell or contact to a foreign object can interfere the calibration.

Page 48: Span Calibration
5.CALIBRATION 5-6-2. Span calibration Span calibration adjusts the instrument’s span (gain) parameters by placing a known weight on the load cell. Enter the known weight value to BALANCE WEIGHT field. To obtain a good linearity, use of a weight heavier than 50% Capacity is recommended. Before performing calibration, make sure unwanted load is applied to the load cell (See “Zero calibration”).
Page 49 5.CALIBRATION 4）Calibration data is stored in non-volatile RAM: allow about 30 seconds before you can turn off the instrument indicator comes on in reversed display while writing data to RAM, then the indicator changes to See "TROUBLESHOOTING" , on page 157 for the details of calibration errors.

Operation MODE EACH CODE → F805AT-BC uses two types of codes: one for weighing (Weighing Code) and the other for settings (Setting Code). 6-8-2. PID control F805AT-BC uses feedback control to control instantaneous feed rate. In this scheme, calculated target value is compared with actual feed rate and the deviation between them is returned to nullify the difference (see the schematic diagram below).
Page 98 6.SETTING AND ADJUSTMENT OF READING Proportion (P) Control rate [%] Wide proportional band (P) makes the [Proportional action] variation of control rate relatively small (smaller slope in the figure to the right), rendering the time required to attain Smaller proportional band equilibrium longer.
Page 99 F805AT-BC is shipped with factory-set initial integration time (I): the user can use this value unless additional tuning becomes necessary.

Re-calibration of zero point is required. Normally, a zero calibration is followed by a span calibration. If the span calibration produces unsatisfactory results, F805AT-BC shows the error message (CAL.ERR.1), indicating that a re-calibration of zero is necessary. Satisfactory re-calibration of zero will remove the error message.
