Sets the operation mode for remote input 1 terminal. Choices are as follows:
•
NONE
- If this option is selected then remote input 1 will have no function.
•
P.HoId
- 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.HId
will appear briefly every 8 seconds whilst the input terminals are short
circuited to indicate that the peak hold function is active. All active channels will be peak held when this
mode is chosen and activated.
•
d.HoId
- 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. All active channels will be display held when this mode is
chosen and activated.
•
P.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, a
rSt
message will be seen if the memory is reset by holding a short circuit for 2 to
3 seconds. The peak high mode will operate on all active channels.
•
P.Lo
- valley memory. The minimum value stored in memory will be displayed. Otherwise operates in the
same manner as the
P.Hi
function described above. The peak low mode will operate on all active channels.
•
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. The peak high/low mode will operate on all
active channels.
•
AI.AC
- alarm acknowledge. Allows the remote input to be used to acknowledge an alarm. If the alarm is
set for latching operation the acknowledgment will allow the alarm and any relays allocated to that alarm to
reset when the alarm condition is removed. If the alarm is set for automatic reset the acknowledgment will
allow the alarm and any relays allocated to that alarm to reset even if the alarm condition still exists this could
typically be used to silence a siren controlled by a relay even though the alarm condition is still present. The
acknowledge will operate on all alarms programmed to require acknowledgement.
