Hand-held Analyzer Types 2250 and 2270 – User Manual

16) Secondary Microphone: This is used to add recorded comments to measurements and is

positioned on the underside of the analyzer.

17) Top Socket: This is the main microphone input socket for the analyzer. The measurement

microphone and preamplifier (items 1 and 2 respectively) are normally connected directly

to this socket. For more details see section 2.3.

18) Tripod Mounting Thread: Use this to mount the analyzer onto the tripod and/or tripod

extension.

19) Wrist Strap/Tripod Mounting Thread: Use this to attach the wrist strap to the analyzer

for added security, or use it to mount the analyzer onto the tripod and/or tripod extension

using Tripod Adaptor UA-1673.

20) Internal Battery Pack: Rechargeable, high-capacity Li-Ion battery pack to power the

analyzer.

21) Hinged Cover FB-0679/FB-0699: A removable plastic cover is provided, which is hinged

at the top to provide protection for the connector panel underneath. To remove, open the

cover and pull the hinge out of the slot at the top of the connector panel. The cover

includes a rubber insert printed with an overview of the main connectors and reset button for

easy recognition. Indents are provided on the inside of the cover (behind the insert) that

allow you to drill holes in the plastic cover, giving access to the main connectors

underneath, so you can use the cover while power or other cables are connected.

22) Camera (Type 2270 only): This feature is used to add images to measurements. Protected

and positioned on the underside at 45 degrees, this is designed to allow simultaneous image

capture and noise measurement without the need to reposition the analyzer for each task.

23) High Speed USB and LAN Interfaces:

– Hardware versions 1 – 3: Available in Type 2270 only

– Hardware version 4 (G4): Available in both Types 2250 and 2270

This is used to provide fast and seamless transfer of data, recordings and photographs back

to the office. Both high-speed interfaces, USB or LAN, can be used when the analyzer is

located in close proximity to the PC. However, if the analyzer is remote from the host PC,

the LAN interface has the further advantage of data download from anywhere within the

same LAN network. Both interfaces are not just used for data download, but also for

remote monitoring and remote control.

24) G4 Mark: Indicates that the hardware is version 4. Without this mark, your hardware is an

earlier version
