relay operates. For larger increments, use a
larger percentage.
Pulse Time On (cyc) This value is used to control how long the output
pulse is on during an Instantaneous pickup test.
This value is in cycles. Note: Set Pulse Time On
slightly greater than the operating time of the
relay.
Pulse Time Off (cyc) This value is used to control how long the output
pulse is off during an Instantaneous pickup test.
This feature is required in order to protect the
relay under test against excessive heating due
to applying large currents continuously. This
value is in cycles. Note: Start with equal
amounts of Pulse Time On and Off.
Target & Seal-In Ramp Specifications
Increment % / 100msec This value is used to control the how fast the
MPRT will increase the current to determine the
pickup value for the target and seal-in. The
value input into this field is in % increase per
100msec. The default value for this field is .02
% of pickup. Example: If the pickup is set for 2.0
amperes the MPRT will increase the current
magnitude 0.0004 amperes every 100msec until
the relay seal-in contacts close.
