5.38 Remote input function
Display: R.INP
Range: NONE, P.HLd, d.HLd, Hi, Lo , HiLo, tARE, ZERO, SP.Ac, No.Ac ,
CAL.S, P.SEt, duLL or O.Put
Default Value: NONE
Remote input function - When these remote input terminals are short circuited, via a switch, relay,
keyswitch etc. the instrument will perform the selected remote input function. A message will
flash to indicate which function has been selected when the remote input pins are short circuited.
The remote input functions are as follows:
NONE - no remote function required i.e. activating the remote input has no effect.
P.HLd - peak hold. The display will show the peak value (highest positive value) only whilst the
remote input terminals are short circuited i.e. the display value can rise but not fall whilst
the input terminals are short circuited. The message P.HLd will appear briefly every 8
seconds whilst the input terminals are short circuited to indicate that the peak hold function
is active.
d.HLd - display hold. The display value will be held whilst the remote input terminals are short
circuited. The message d.HLd will appear briefly every 8 seconds whilst the input terminals
are short circuited to indicate that the display hold function is active.
Hi - peak memory. The peak value stored in memory will be displayed if the remote input
terminals are short circuited, if the short circuit is momentary then the display will return
to normal measurement after 20 seconds. If the short circuit is held for 2 to 3 seconds or the
power is removed from the instrument then the memory will be reset.
Lo - valley memory. The minimum value stored in memory will be displayed. Otherwise operates
in the same manner as the Hi function described above.
HiLo - toggle between Hi and Lo displays. This function allows the remote input to be used to
toggle between peak and valley memory displays. The first operation of the remote input will
cause the peak memory value to be displayed, the next operation will give a valley memory
display. P Hi or P Lo will flash before each display to give an indication of display type.
tARE - display tare. Short circuiting the remote input pins momentarily will allow toggling
between nett and gross values (shown as NEtt and GROS). If the remote input is short
circuited for approx. 2 seconds the display will be tared and will show zero. The tare will be
lost if power is removed.
ZERO - display zero. Zeroes the display in same manner as the tare function except that the zero
is not lost when power is removed and the display will zero as soon as the remote input is
shorted. When the ZERO operation is used the gross value cannot be recalled and the input
at the time of the ZERO operation will become the new zero point.
SP.Ac - setpoint access only. This blocks access to any functions except the alarm setpoint
functions unless the remote input pins are short circuited or entry is made via CAL mode or
if the ACCS function is set to ALL.
No.Ac - no access. This blocks access to all functions unless the remote input pins are short
circuited or entry is made via CAL mode or if the ACCS function is set to ALL.
