The "SETUP" functions of the 4030's six front panel buttons have been
described in Section 1.f. These are the functions labelled on the
buttons themselves. The "RUN-TIME" button functions are as follows:
BUTTON No. 1 ("LIVE DISPLAY"):
Each Push: Calls Channel 5 ("LIVE" INPUT WITH TARE) to digital
and bargraph display. Under the "standard configuration," the "F1"
indicator will
always be on when the 4030 is in "RUN-TIME" mode.
BUTTON No. 2 [NOT ASSIGNED]:
This button has no assigned "run-time" function in the "standard"
4030 configuration.
BUTTON No. 3 ("TARE"):
Each Push: Zeroes Channel 5 ("LIVE" INPUT WITH TARE) so that
subsequent readings of Channel 5 will represent the value of
Channel 1 ("LIVE" INPUT)
minus the existing value of Channel 1
(now stored as a constant "tare" offset).
BUTTON No. 4 ("MAX/MIN/MAX-MIN STEP"):
Each Push:
If Channel 5 is currently on display, displays Channel 6 ("MAXI-
MUM" VALUE OF CHANNEL 5) and lights the "F3" indicator.
If Channel 6 is currently on display, displays Channel 7 ("MINI-
MUM" VALUE OF CHANNEL 5) and lights the "F4" indicator.
If Channel 7 is currently on display, displays Channel 8 ("MAX
minus MIN" VALUE OF CHANNEL 5) and lights the "F5" indicator.
If Channel 8 is currently on display, displays Channel 5 ("LIVE"
INPUT WITH TARE) and lights the "F2" indicator.
BUTTON No. 5 ("MAX/MIN RESET"):
Each Push: Resets the "MAX"- and "MIN-" measuring functions of
Channels 6 and 7, respectively, momentarily setting each of these
channels equal to the current "live" reading of Channel 5.
BUTTON No. 6 ("SETUP")
First Push: Enables "SETUP MODE" for the selected channel (see
Section 1.f). Causes the "SETUP" indicator to light.
Second Push: Disables "SETUP MODE" for the selected channel
(see Section 1.f). Turns off the "SETUP" indicator.
