Hand-held Analyzer 2250 Light – User Manual

Connecting a Microphone Extension Cable

There are two optionally available extension cables which are recommended for use with

2250 Light. These are:

• AO-0697-D-030: 3 m long

• AO-0697-D-100: 10 m long

Note: Connecting a recommended microphone extension cable has no appreciable effect on the

Hand-held Analyzer’s measurement and has no effect on the instrument’s calibration.

However, although it is not essential to re-calibrate, it is good measurement practice to calibrate

the whole measurement chain (including microphone extension cable) before starting a

measurement.

Decide which cable you require and assemble as follows:

1) Gently screw Microphone Type 4950 onto Preamplifier ZC-0032 (see items 1 and 2 in

Fig.2.1).

2) Insert the preamplifier into the female plug of the extension cable and push gently until it

snaps into position.

3) Insert the male plug of the extension cable into the top socket of the Hand-held Analyzer (see

item 17 in Fig.2.1) and push gently until it snaps into position.

Mounting the Measurement Microphone on the Microphone Holder and Tripod

Mount the microphone and preamplifier combination onto Microphone Holder UA-1317 and

Small Tripod UA-0801, as follows:

1) Set Small Tripod UA-0801 in the required position, and adjust to the required height.

2) Screw Microphone Holder UA-1317 onto the threaded stud on the tripod ball-joint, and

position the holder as required.

3) Push the microphone and preamplifier combination carefully into the microphone holder, so

that it grips onto the body of the microphone and preamplifier. Ensure that the microphone

lead sits properly in the plastic guide.

Once you have carried out these instructions, you are ready to start measuring, see Chapter 3.

2.5.4 Measuring for Convenience

Measurements that need to be done at short notice, with no particular accuracy can be carried

out by simply holding the instrument or using any combination of hardware components and

accessories shown in Fig.2.4.
