Supplemental Operator’s Guide

• Toggle the [XDCR UNIT ON OFF] softkey (F4) until ON is highlighted.

•Press the [XDCR UNIT LABEL] softkey (F7).

•Select the [g] softkey (F2).

Setting Up Input Range

Use CH* AUTO UP ONLY as the autorange routine as follows:

•Press the [Input] hardkey.

•Press [ALL CHANNELS] softkey (F2).

•Select the [CH* AUTO UP ONLY] softkey (F5).

Then tap the structure with the hammer once. A yellow overload light by the input BNC connectors will indicate an overload, and the range will increase one step. Continue tapping on the structure, one tap at a time, allowing time for the input range to increase, until an overload is no longer indicated. This may take many hammer strikes. When an overload on either channel is no longer indicated, then the ranges are set correctly.

Choosing a Preliminary Frequency Span

Setting up a frequency response measurement is an interative process. A span is selected, a measurement is made, and the results are examined to determine if a narrower or wider span is required. To start measuring frequency response, you must select an initial span:

•Press the [Freq] hardkey.

•Enter 1600 and then press the [Hz] softkey (F2).

Note: span should be any frequency that encompasses all modes of interest. If in doubt, start with a wider span.

Specifying Trigger Parameters

Hammer testing is triggered by the signal from the hammer. Without a force transducer, the trigger must come from the accelerometer that is attached to the hammer and connected to Channel 1. To set up a Channel 1 trigger, follow these steps:

•Press the [Trigger] hardkey.

• Press the [CHANNEL 1 2 3 4] softkey (F3) until 1 is highlighted.

•Press the [TRIGGER SETUP] softkey (F6)

•Press the [CHANNEL LEVEL] softkey (F1)

•Enter 5 then press the [PERCENT (%)] softkey (F4)

•Press the [SLOPE POS NEG] softkey (F5) until POS is highlighted.

•Press the [Trigger] hardkey.
