3.6 Display Hold Connections
The ÒDisplay Hold" function can be used to freeze the display.
Connect a single pole, single throw (SPST) switch between pins
1 and 2 on the P2 connector. The display will stop updating when
this switch is on. When this switch is off, the display will update
itself 2.5 times per second.
To access the ÒDisplay Hold" function, attach copper wire to the
3-pin female connector that is supplied with the meter. Refer to
Figure 3-10 for wiring instructions. This connector shares a
common return with the Analog Output. Plug the female
connector into the P2 connector at the rear of the meter.
Figure 2-2 shows the location of the P2 connector on the meter.
