Mode
Operation
run
(run)
The run option allows accumulated time display. The mode operates in the
following manner:
Input inactive: The timer stops but holds the time display.
Input active: The timer continues timing from the previous time i.e. the time
accumulates.
dur
(duration)
The duration option allows display of an input time with a reset at the end of
the input. The mode operates in the following manner:
Input inactive: The timer is automatically reset and the display shows zero or
the preset value.
Input active: The timer starts timing from zero or the preset value.
PLSE
(pulse)
The pulse option allows timing of the duration of an input pulse. The mode
operates in the following manner:
Input inactive: The display will hold the time of the last pulse.
Input active: The display resets to zero (preset does not apply to this mode)
then starts timing the new pulse.
SnGL
(single pulse)
The single pulse option allows timing of the duration of a pulse. The mode
operates in the following manner:
Input inactive: The display will hold the time of the last pulse. The display
must be reset before a new pulse can be timed.
Input active: If the previous time display has been reset then the timing pro-
cess will start from zero or the preset value. If the previous display has not
been reset the value displayed will not change when the input becomes active.
PLS.H
(pulse held)
The pulse held option operates in the same manner as the
PLSE
option with
the exception that the display indication only changes at the end of the active
input i.e. the previous display is held until the new active input ends.
SnG.H
(single pulse held)
The pulse held option operates in the same manner as the
SnGL
option with
the exception that the display indication only changes at the end of the input
pulse. As with the
SnGL
option the display must be reset before a new pulse
can be timed.
UP
(up timer)
The up timer option allows the instrument to be used as a timer with a start,
stop and reset input. The mode operates in the following manner:
Upon receiving an active input the display will show accumulated time. This
timing will continue until a STOP input is received even if the input becomes
inactive. This STOP input is operated via an edge between the Input 2 IN
and GND terminals. A reset input will reset the timer to zero. If the timer is
stopped and then restarted without a reset the timing will continue from the
previous time.
dn
(down timer)
The down timer works in the same manner as the UP timer with the exception
that the down timing will automatically start from the time set at the
P.SEt
function.
d.run
(down timer run mode)
The mode operates in the following manner:
Input active: Display starts timing from preset value or the previous time
recorded. Input inactive: Display holds time. A preset (or reset to preset)
operation must be carried out when the time needs to be reset.
