Operation

This section gives examples of how to connect and use the

instrument. Before you start:

• Read and understand the "Safety" section.

• Do not use a damaged instrument.

Operation - Frequency connections

To prevent instrument errors, make sure that the

frequency connections (A1-item [10]) are correct.

Operation - Communications port connections

Use the communications port (A1 - item [9]) to attach an

IDOS Universal Measurement Module (UMM).

When you attach the cable from a UMM (Figure 7/8), the

instrument automatically changes the menus to give you

all the applicable options (Table 2/3).

Operation - Measure Hz or count pulses

To measure Hz or count pulses:

1. Connect the instrument (Figure 1) and, if necessary,

adjust the Set Up (Table 1).

2. Select a Hz or Pulses input task from Select Task

(Table 2/3) and, if necessary, adjust the Settings

(Table 4).

3. For Pulses, use Start/Stop (■ ■) to start and stop the

count. The display shows the time (hh:mm:ss) since you

started the count.
