TIME A

1.1.2.2

RATE (Cont'd)

gate time interval is selected by the combination of front panel thumbswitches and multiplier.

Accuracy is 1 count time base accuracy. Gate times are:

to 9.99999 sec

.000001 to .999999

.000001 to .999999

X1000

1.1.2.3

TIME A

This mode is essentially a multiple period average measurement of either Input A or the

FLOWMETER input. The number of periods averaged is selected by the front panel

thumbswitches and the clock resolution is selected by the multiplier as follows:

Multiplier

Accuracy is 1 count, time base accuracy trigger error.

1.1.2.4

TIME INT.

This mode allows the unit to measure the duration of a mechanical or solid state switch

closure, the time between two momentary external switch closures, the time between two

external pulses, or the time between two actuations of a single front panel switch. Clock

resolution is again selected by the multiplier switch as in 1.1.2.3. Accuracy is same as TIME

A mode.
