Chapter 2 - Test Set Operation
2.1 INTRODUCTION
This chapter refers to local operation of a GPSG-1000 configured with factory default
settings unless specified otherwise. New Test Sets are configured to start in the factory
default setting. Review Installation and Power Requirements before using the Test Set.
2.2 POWER REQUIREMENTS
2.2.1 Power
The GPSG-1000 is powered by an internal Lithium Ion Battery. The battery charging
circuit enables the operator to recharge the battery anytime the unit is connected to the
DC power supply. The GPSG-1000 can operate continuously utilizing the DC power
supply. The internal battery is equipped to power the GPSG-1000 for four hours of
continuous use.
2.2.2 AC Power Requirements
The DC Power Supply supplied with the GPSG-1000 operates over a voltage range of
100 to 250 VAC at 47 to 63 Hz. The battery charger operates whenever DC Power
(11 to 32 Vdc) is applied to the Test Set with the supplied DC Power Supply or a suitable
DC power source.
NOTE: I f the supply voltage is <11V, the unit will switch to internal battery. If the voltage
is >32V, a 7 AMP resettable fuse on the DC input port will open, protecting the Test Set.
When charging, the battery reaches a 100% charge in approximately four hours. The
Battery Charge temperature range is >-10° to <60°C, controlled by an internal battery
charger.
