The "pick up" of a relay is a setting at which the relay will begin to operate. Such as an overcurrent relay - if the pickup is set to 5A, when 5A is flowing through the relay, the relay will operate.
A definite time over-current relay operates like an instantaneous over-current relay coupled with a timer. Once current reaches the pick-up value, it initiates the timing circuit. As long as current stays above this pick-up value, the timer will continue to time. Once the definite time setting is reached, the relay gives trip signal to the circuit breaker.
The way you check to see if an under voltage relay is wired properly is to disconnect the electrical supply. If the device that is connected to the load side of the relay does not start up or energize when the electrical supply is reconnected, then the relay is connected correctly.

Pick up current is the minimum current required to initiate the operation of a relay and close its contacts. It is the threshold current level at which the relay switches from its deactivated state to its activated state.
the blinker relay is behind the glove box
In the under hood relay/fuse center.
This is basically a differential relay that contains an additional restraining coil with the operating coil connected at its midpoint used to prevent the unnecessary pick up of the relay.
it's in the glove box!
Are you sure you pulled the right relay?
The pick-up value of an electromechanical relay is the minimum current or voltage required to activate the relay and close its contacts. In contrast, the reset value is the minimum current or voltage needed to de-energize the relay and return it to its original state. These values are crucial for ensuring proper operation and timing in control circuits, as they determine the relay's responsiveness to input signals.
