Section III

OPERATION

3.1

Capabilities

The Anadex Model CF-604-6-8175Q, Flow Indicator, has widespread versatility and may be operated in any of

the following modes: RATE (Frequency), TIME A (Period), TIME (EXT) PRESET COUNT and REMOTE control.

To assist in determining which mode to use, Section 1.2 of this manual contains typical applications for each

operational mode.

3.2

Mode Selection

3.2.1

Mode Selector Switch

The Mode Selector Switch setting determines the operational function of the counter. There is a

position for each of the modes mentioned in paragraph 3.1 and in addition a setting is included for

TEST. Each of the paragraphs in Section 3.3 discusses a particular mode of operation in detail.

3.2.2

INPUT A MULTIPLIER

The INPUT A MULTIPLIER consists of a three position input signal attenuator (X1, X10, X100) and a

concentric FINE vernier control. Before operating the counter in any of the selected ranges, check the

specifications, Section I, for maximum allowable signals. Usually it is desirable to operate with the

highest possible sensitivity (X1 or X10) within the limitations of maximum allowable signal level.

However, when the input signal contains unwanted noise, it is sometimes necessary to decrease

sensitivity.

3.3

Operational Modes

Check Section I of this manual for details on when to use specific modes and their accuracy limitations.

3.3.1

RATE (Frequency) Measurements

Frequency and Rate are synonymous terms for this mode of operation where actual measurement is of

repetition rate, cycles or frequency per unit of time. Fold out Dwg. #0100-5097-01 for assistance in

determining control and terminal locations.
