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 to10 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.
Aeroflex 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:
O Have a qualified electrician check
receptacle(s) for proper grounding.
O 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.
1.4.4 CAUTION and WARNING Labels
Exercise extreme care when performing
operations preceded by a CAUTION or
WARNING label. CAUTION labels appear
where possibility of damage to equipment
exists. WARNING labels denote conditions
where bodily injury or death may result.
