Activating the power output, closing a monitored contact or detect-
ing a voltage drop are
positive
events. Positive events are labeled
with an
upward ( )
arrow.
Automatic disconnection of the power output, opening a closed
contact of clearing an existing voltage at the monitor inputs are
negative
events. These are labeled with a
downward ( )
arrow.
A wide choice of combinations between positive and negative events provide
great freedom to accommodate various test conditions and relay types by
selecting the class of event that must start or stop the instrument’s timer or
the power output. If, for example, the operation contact of the tested relay is
connected to a circuit under voltage, you can connect it in parallel to the
black and red monitor connectors and select a
negative
event for the timer’s
STOP mode, since any voltage present between these connectors will disap-
pear when the contact is closed upon relay’s operation.
You only need to press the
button sequentially to toggle among the
timer’s various START/STOP event combinations.
Pulse Length Measurement
Timer
start
is usually associated with some action on the power output
switch, but an additional special mode allows the timer to be started
and
stopped when monitor changes occur. This is the
pulse length
measurement
mode, with two options:
positive
and
negative
pulse. Select
positive
(
)
pulse
to measure the time lapse between activation and deactivation of the
monitor. Select
negative (
)
pulse
to measure between the deactivation
and re-activation of the monitor.
Remember: monitor activation is signaled by the red LED labeled “Monitor”
on the left of Display #1.
SPECIAL MEASUREMENT AND CONTROL FUNCTIONS
A number of convenience features have been built into the PTE-100-C PRO
to make its operation easier, sometimes saving the user from carrying addi-
tional instrumentation.
Access to these functions is located in a shaded area underneath Display
#1, which is used to view measured values and to enter control settings.
