Quick Start Guide for AV3680A Handled Cable & Antenna Tester 

 

 

Chapter 2 Ready for Use 

AV3680A  Handheld  Cable  &  Antenna  Tester  is  designed  with  exquisite  appearance  and  comfortable 
operation. It has smaller volume, with the largest overall dimension being only 205mm (H) × 295mm (W) 
×  70mm  (D);  and  lighter  weight,  with  the  single  unit  weighing  totally  about  2.5kg  (including  battery), 
which  is  easy  to  carry  for  field  test.  This  Chapter  will  emphatically  introduce  the  instrument’s  test 
environment, power supply, structure and battery replacement. 

 

2.1 Pre-operation Preparation 

This  Section  will  describe  the  precautions  before  initial  use  of  AV3680A  Handheld  Cable  &  Antenna 

Tester. It meets the requirements of security specified in GJB3947A-2009, please read the following safety 

instructions carefully to avoid damage to the instrument or unnecessary personal injury. 

 

 

To  prevent  damage  to  the  instrument,  avoid  electric  shock,  fire  and  personal 

injury: 

 

Do not open up the instrument without authorization 

 

Do  not  attempt  to  disassemble  or  modify  any  part  not  described  in  this 

manual.  If  disassemble  it  at  your  own  discretion,  it  may  cause  various 

consequences such as degradation of electromagnetic shielding performance 

and  damage  to  internal  parts,  thus  affecting  product  reliability.  If 

disassemble  it  without  authorization,  even  during  the  warranty  period,  we 

will no longer provide free maintenance. 

 

2.1.1 Environmental Requirements 

 

To ensure the service life and validity and accuracy of AV3680A, please conduct testing under the 

following conditions: 

 

1.  Temperature  range:  Storage  temperature  range:  -40℃  ~  +70℃;  operating  temperature  range:  -10℃  ~ 

+50℃ 

 

2.Low air pressure: 

 

Low air pressure (altitude): 0 ~ 4600m 

 

2.1.2 Power Supply Requirements 

 

AV3680A can be powered in three ways: 

 

1

Powered by AC power supply and adapter
