INSTALLATION ENVIRONMENT

devices that generate excessive heat should be avoided.
Do NOT use solvents. Continuous exposure to direct sunlight may accelerate
the aging process of the bezel.

by the Apollo current meter can be scaled
down to almost any lower numerical value
by connecting the scale adj. pot. This pot
can be set to divide the normal numerical
current reading by any division factor
between ÷1 and ÷13. In addition, the shunt
resistance chosen can be reduced by
connecting the current lead to a lower
resistance (higher range tap).

Consideration should be given to the thickness of the panel. A panel which is
too thin may distort and not provide a water-tight seal. (Recommended minimum
panel thickness is 1/8".)

EXAMPLE
measure a circuit current to 120.0 mA maximum. However, in this application,
the readout is to be in percent of load current, with 120.0 mA being equivalent
to 100.0% readout. The scale adj. pot. connected as shown can be adjusted to
reduce the normal 120.0 mA display to the 100.0% display desired. The input
current leads could also be connected to 4 and 3 instead of 5 and 3 as shown,
and this would yield a readout to 100% and allow the decimal point and least
significant digit (0.1%) to be dropped.
current can also be done in most cases by simply feeding the current input into
a lower range. However, at the higher current range (1.999 A) and with external
shunts, care should be taken to avoid exceeding maximum shunt current.
(current flowing between terminals 3 and 4), the numerical current value will

to say 1.500 by connecting to the next sensitivity (199.9 mA) since the 1.3 amp

“Specifications” for maximum current.)
