DIALOGUE PIN
Enables activation or de-activation of the PINLOCK.
Press I to scroll through Unloc , Loc . Unlock deactivates the PIN so that entry to setup and
calibration menus is possible. However it does not override the hardware lock in the FAD.
Press P to enter the displayed item.
The display shows 000000. Key in the PIN number and press P .
If the number entered was correct the display shows PASS briefly and returns to the calling menu.
If the number entered was incorrect the display shows FAIL briefly and returns to the calling menu.
The selected Lock or Unlock position is not automatically saved in EEPROM but following a
subsequent STORE operation. (See Fn 40 for instructions on how to change PIN)
After the calibration of the unit is completed return to PIN dialogue to lock.
DIALOGUE Par (Scale Parameters of FAD)
The dialogue PAR is used to select scale parameters. When PAR is selected RTD-52 uploads
the parameters in use in the connected FAD. The parameters are defined as follows :
2.P = Position of decimal point (Nr of decimal digits). (0-4)
3.P = Display resolution (1-50)
4.P = Two first digits of weighing range (00-99)
5.P = Digital filter. (If entry is x then samples = 2 x ). (0-4), (0-2 for FAD-4)
6.P = A/D converter speed (1-4)
1 = 8 / n , 2 = 20 / n , 3 = 40 / n , 4 = 80 / n conversions per second.
n = Nr. of load cells. The max. conversions per second can not exceed 40 for FAD-4.
7.P = No motion samples. (If entry is x then samples = 2
x
). (1-7)
8.1 = Autozero maintenance 0 = NO 1 = YES
8.2 = Autozero on power up 0 = NO 1 = YES
8.3 = Dual digital filter 0 = NO 1 = YES
8.4 = Reserved
8.5 = Reserved
8.6 = Leading zero blank 0 = NO 1 = YES
8.7 = Reserved
8.8 = Loadcell excitation (DWI only) 0 = AC 1 = DC
0.P = Dual interval (00-99)
The first two digits of the weighing range for which the lower display division
will be selected automatically. 00 = Dual interval not active.
GAIN = Loadcell amplifier adjustment 0 = 2 mV/V 1 = 4 mV/V
LCNR = Nr. of loadcells connected (1–4)
Upon exit from PAR, the new parameters are downloaded automatically to the connected FAD,
but not saved in non volatile memory. The calibration audit trail counter will be incremented.
