AM5(e) Classic Instruction Manual

POWER CONSIDERATIONS
2.1
COMMERCIAL POWER
CAUTION: Before connecting the AM5(e) Classic to AC Power , be sure
that the AC power selector switch is in the correct position. For more
details refer to Section 3, sub-sections 3.3.1. and 3.4.1.
All models of the AM5(e) Classic are powered from commercial 115 V AC or 230 V AC
50/60 Hz power, and have a power consumption of 26 Watts (VA). A rear-panel
selector switch selects 115 V AC or 230 V AC.
A detachable 3-wire power cord is furnished which mates with a CCE standard V-type
connector on the rear panel. The other end of the power cord has a standard three-
conductor AC plug. A replaceable 1/2 Ampere fuse is also accessible on the rear panel.
2.2
OPTIONAL BATTERY PACK
The AM5(e) Classic may be equipped with an internal battery pack to allow for full
cordless (no commercial power) operation.
The battery pack consists of two sealed lead-acid batteries and associated charging
circuitry. When fully charged, the batteries will power the AM5(e) Classic for about
five to eight (5-8) hours.
A low battery is indicated by blinking decimal points on the front panel display.
Blinking decimal points indicate about one-half hour of remaining battery power
before recharging is required.
The AM5(e) Classic may be operated while the batteries are recharging. Recharging
occurs continuously whenever the AM5(e) Classic is plugged into AC power whether
the power switch is turned ON or OFF. However, charging will be accomplished faster
when the power switch is turned OFF. Commercial power interruption will not cause
unit to stop operating as long as the batteries remain charged.
2.3
POWER ON AND OFF
The power ON-OFF switch is located on the upper right side of the front panel (refer to
Section 3 for illustration). It is an alternate-action push button. When pushed-in, it will
lock in that position and the power is ON. Push it again, the button will pop out, and
the power is OFF. When the power is turned ON, the AM5(e) Classic will go through a
self-test procedure, then will show factory-set test selections referred to as "defaults".
The operator usually will change these settings for a particular test configuration.
The AM5(e) Classic is equipped with a non-volatile memory for test setups. Although
loss of power will cause operation to cease, current test parameter settings will be
stored in memory. When the AM5(e) Classic is turned back ON, these settings can be
re-established instead of the defaults. A procedure for restoring these settings when
power is turned ON is described in Section 4 of this Manual.
