C.)
The table below specifies which numbered resistances on the circuit board
correspond to the optional low limit and the optional high limit. Solder the appropriate
resistors in these places.
Optional low limit Designated resistors on
circuit board
Low limit fail low R1, R1A (*connected in
series)
Low limit pass safe R2, R2A (*connected in
series)
Optional high limit Designated resistors on circuit
board
High limit pass safe R9, R9A (*connected in series)
High limit fail high R10, R10A, R10B (*connected in
series)
NOTE : Two (three for position 10) resistor locations are connected in series are
provided in case resistors need to be added to achieve the desired total resistance.
Solder a shorting wire across the resistor locations that are not used.
D.) Assemble the unit and mark the appropriate places on the label for the optional
limits.
E.) It is recommended to turn the rotary switch to the optional positions and measure
the resistance from the tip to the body of the plug with an ohmmeter to verify the
resistances.

MAINTENANCE : Wipe the plug periodically with alcohol.
