INTERNAL PARTS REPLACEMENT. All of the internal parts of
an MJ-Series meter lift out as a unit, after the top has been
unscrewed. The lens can then be removed and the internal as-
sembly lifted out. If necessary, turn the meter upside down and
tap one end lightly on a countertop to loosen the internals. The
assembly can be separated by hand.

CONNECTION DIAGRAMS
Diagram 1: Single Sensor Diagram 2: Dual Sensor
NOTE: The Dual Sensor is distinguished by a red stripe on the cable at the
base of the sensor.
MJE or MJHE:
Hall-Effect NOTE: MJ(H)E not available with dual sensor
MJR or MJHR:
Reed Switch
MJR or MJHR:
Reed Switch Black ( - )
White (signal)
Red (+)
To Distinguish Single Sensor From Dual:
Single: (if new from factory) blue wire is cut back on cable end.
Dual: A red stripe will be on cable near sensor.
Note: Dual sensor can be used as a single sensor also - use either the red OR
the blue wire w/black. If using it as a dual sensor then connecting red and blue
together will produce two pulses with every revolution of magnet.
