23.4 When “SPF1/2” is shown, use ZERO to enter set set-point1/2 data mode. When “UNIT.kgf/lbf/n” is shown,
use CELL, PRINT, or UNIT key to select unit of input force number. After this, use CELL, PRINT, UNIT
key to input force number, and then use ZERO to confirm and save them.
23.5 In normal force measure mode, if SPF1 or SPF2 is set bigger than 0, the electronic level on output line will
change according to the setting of OUTx.yz.
23.6 Press SELECT key to return to last menu item, press ON/OFF key to prepare to exit this mode
24. Analog Voltage Output Setup
Note:
The current draw from analog voltage output should be less than 2.5mA, that means the resistor
added on this output connector should more than 1K
M
!
24.1 Press down SELECT until CONFIG is shown, using PRINT or CELL key to select IN.OUT-AVOUT item,
press ZERO to enter this mode.
24.2 Use CELL or PRINT key to select MODE (set analog voltage output is enable or disable) or 2.5V-F (set
the force number of 2.5V output) or CAL.VO (calibrate the output analog voltage). Use ZERO to confirm.
24.3 After enter MODE item, use CELL and PRINT to enable or disable output analog voltage, Use ZERO to
confirm.
24.4 After enter 2.5V-F item, “UNIT.kgf/lbf/n” will be shown, use CELL, PRINT, or UNIT key to select unit of
input force number, then use CELL, PRINT, UNIT to input force number that is corresponding to the 2.5V
analog voltage output, Use ZERO to confirm.
24.5 When CAL.VO is shown, it means calibrate output voltage. Before this, a high accuracy voltage meter is
need. After enter this calibration mode by pressing ZERO key, “0.0000V” will be shown, that means output
0.0000V is ready to be calibrated. if the reading on voltage meter is not 0.0000V, use CELL or PRINT to
adjust the reading to 0.0000V, then use ZERO key to finish 0.0000V output calibration. Similarly, do
calibration on 1.2500V and 2.5000V. When adjust the output voltage, the output code to DAC (Digit to
Analog Converter) will be displayed temporally and then back to display output voltage.
24.6 Press SELECT key to return to last menu item, press ON/OFF key to prepare to exit this mode
25. Details about Serial Communication
25.1 COM1 is RS232, communication wires come from RS232 connector, and TXD1, RXD1 and GND are
used.
25.2 COM2 can be RS232 or RS485, if used as RS232, communication wires come from RS232 connector,
and TXD2, RXD2 and GND are used, if used as RS485, communication wires come from RS485
connector, and A and B are used (if need GND or +5VCC1 can be used).
Please refer to section 26.2, 26.3.4-5, 26.3.7-9 for jumper connector details.
25.3 The baud rate and byte format is set by USER-COM1/2-BAUD.RT and USER-COM1/2-BYT.FMT.
Responses to serial commands will be immediate, or within one force measure cycle of the indicator. One
second should be adequate for use as a time-out value by remote (controlling) device.
25.4 The length of each item in a transition string:
25.4.1 Reading data --- 6bytes
Data polarity ----1byte: “-” for negative, and followed the first digit; “ ” for positive.
Decimal point ---1byte: “.”
