SECTION 2 - OPERATION
1. INSTALLATION
1.1 GENERAL
The Test Set is powered by an internal
battery. The Test Set contains a battery
charging circuit which enables the operator
to recharge the battery when connected to
ac power.
NOTE: The Test Set can operate
continuously on ac power for
servicing and/or bench tests.
Refer to 1-2-2, Figure 2 for location of
controls, connectors or indicators.
1.2 BATTERY OPERATION
The internal battery (NICAD) is equipped to
power the Test Set for two hours of
continuous use, after which time, the Test
Set battery needs recharging.
The 0 to 30% scale displays battery
voltage. Normal battery charged condition
is indicated as 15 V or greater. Less than
12.5 V indicates a discharged battery. An
automatic low voltage cutoff circuit turns
the Test Set OFF when the battery voltage
drops under 12.5 V.
The Test Set contains an automatic time-
out to conserve power. An automatic timer
turns the Test Set OFF after 6 to
10 minutes (only when using battery
power). The Test Set can be recycled by
pressing the PWR/BAT Switch to the BAT
position.
1.3 BATTERY CHARGING
The battery charger operates whenever ac
power is applied to the Test Set. The
battery should be charged every three
months (minimum).
NOTE: Overnight charging is
recommended.
1.4 SAFETY PRECAUTIONS
The following safety precautions must be
observed during installation and operation.
IFR Systems, Inc. assumes no liability for
failure to comply with any safety precaution
outlined in this manual.
1.4.1 Complying with Instructions
Installation/operating personnel should
attempt to install or operate the Test Set
only after reading and complying with
instructions contained in this manual. All
procedures contained in this manual must
be performed in exact sequence and
manner described.
1.4.2 Grounding Power Cord
WARNING: USE OF A THREE-PRONG TO
TWO-PRONG ADAPTER PLUG
CREATES A SHOCK HAZARD
BETWEEN THE CHASSIS AND
ELECTRICAL GROUND.
For ac operation, the power cord, equipped
with standard three-prong plug, must be
connected to a properly grounded three-
prong receptacle. It is the customer’s
responsibility to:
● Have a qualified electrician check
receptacle(s) for proper grounding.
● Replace any standard two-prong
receptacle(s) with properly grounded
three-prong receptacle(s).
1.4.3 Operating Safety
Due to potential for electrical shock within
test equipment, the Chassis Assembly must
remain installed in the Case Assembly.
Battery replacement must only be
performed by qualified service technicians.
