TIME-EXT. (Interval) Measurements

3.3.2

(Cont'd)

D. Other Front Panel Controls

POWER Switch - See Section 3.3.1,C.

RESET Pushbutton - See Section 3.3.1, C.

DISPLAY TIME Control - See Section 3.3.1,C.

INPUT MULTIPLIER - See Section 3.2.2 above.

MEM. SW - Engages (ON) or disengages (OFF), the memory logic. In ON position, the display is

updated automatically at the end of each count cycle ONLY, when in the particular operating mode

reset also occurs automatically. Switch must be in OFF when gating is by START-STOP SW or

STARTSTOP DC control signals as described above. In OFF, the display continually follows the

counting process.

COUNT ON/OFF Switch - Not used in this mode.

E. Rear Panel Connections

A (BNC) - The input signal for some of the TIME measurement modes is applied to this connector.

FLOWMETER Conn. - Not normally used in this mode.

REF.1 MHz BNC - Test point for calibration of internal oscillator.

CONTROL Connector - See Section 3.3.1,D.

EXT. RESET SW or PULSE Pins - See Section 3.3.1, D.

F. Rear Panel Controls

A/FLOW Switch - See Section 3.3.1,E. Not normally used in this mode.

EXT. T. B./INT. T. B. Switch - See Section 3.3.1,E.

3.3.3

TIME-EXT. (Interval) Measurements

This mode allows measurement of phenomena such as DC level changes, switch closures and pulse to

pulse spacings which would more easily be applied to the rear CONTROL connector. NOTE: All of

Section 3.3.2 applies except para.3.3.2B.

A. Front Panel Controls

POWER SW. - See Section 3.3.1, C.
