AC Line Operation 

 

The PSAxx02 can be operated continuously from mains power using the 
AC power adaptor provided by Aim-TTi.  This also recharges the 
internal battery. 

Input Voltage Range:  100V to 240V nominal 50Hz/60Hz.  Interchangeable plus for UK, Euro, 

USA and Australia are supplied. 

12.1.11 

Battery Operation 

 

The PSAxx02 operates from internal rechargeable batteries.  The 
batteries are recharged using the AC power adaptor supplied. 

Battery Type: 

Li-ion 3.7V, 3Ahr nominal 

Battery Life: 

> 8 hours continuous operation 

Recharge Time: 

< 3 hours from fully discharged 

Auto-Sleep Mode: 

To conserve battery life, the system can be set to automatically switch 
into sleep mode after a defined time from the last key press.  This can 
be set between 5 mins and 60 mins (or never).

Tilt Stand: 

Built-in tilt stand for bench use which angles the unit at approximately 
40 degrees to the horizontal. 

Screen Protector 

For portable use, the tilt stand can be moved from the rear of the 
instrument to the front where it acts as a screen protector and sun 
shield.
