With the 4314AF
Valhalla introduces an added safety feature that prevents
the possibility of having the charging adapter connected
while using the instrument for measurements.
A 6-pin
Mil-Spec circular connector (MS3112E10-6S) on the front
panel of the 4314AF replaces the four-terminal banana
jacks used on the 4314A front panel and the battery
charger jack on the 4314A rear panel. This is
accomplished by the removal of the rear panel charger
jack and including its connections to the instruments
charging circuits through the 6-pin front panel
connector. Four of the front panel connector pins are
used to mate with the measurement adapter cable and the
other two pins are for the battery charging cable
adapter.
By using
separate adapter cables for measurements and charging of
the batteries, it ensures that the charge circuit can not
be activated at the same time as measurements are being
made.
Measurement
Adapter Cable:
The measurement
adapter cable is a 3 feet long cable with a 6-Pin
Mil-Spec circular connector, "MS3116F10-6P" at one end
and a 4-Pin Mil-Spec circular connector at the other end.
The cable configuration is two twisted pairs with an
outer shield. The four wires are connected to four of the
connector pins that mate with the front panel connector
pins used for 4-wire measurements.
Battery
Charging Cable:
A standard
115VAC input wall adapter with an output of 6VDC at 300mA
is used for charging the 4314Af batteries. The adapter
has a 3 feet cable that the 6-Pin Mil-Spec connector has
been attached to. Removing the measurement cable from the
4314AF and connecting the 6-Pin connector of the power
adapter cable to the 4314AF front panel connector allows
the batteries to be charged.
