@ GATE TIME/MULTIPLIER

For setting the gate time (CHECK, FREQ. A, FREQ. B) or average mea

surement time multiplier (PERIOD, T.I., RATIO). Each time (E>) is

pressed, the lamp indication shifts 10 ms/10° -* 0.1 s/101 -> 1 s/102 -*

10 s/103 -*■ 10 ms/10° -> . . . cyclically, and the gate time or the multi-

plier is set to the value indicated by the lighted lamp. When [ w ] is

pressed (the lamp within the switch goes on), counting is made once,

then stops. Each time RESET is pressed in the hold state, a counting

is made, then stops. When [~lq ] is pressed again, the lamp within the

switch goes off and the hold function is deactivated. RESET initializes

the operation of this unit (without changing the functions).

@ RMT

The lamp goes on when this unit is in the remote state. In this case, no

operation is made when a panel switch is pressed. (For GPIB remote

control)

@ AC 100 V

Indicates the available voltage. Use 100/120/220 V ac at ±10%,

or 240 V a c+4%,-10%.

@ T0.4A

Indicates the rating of the fuse in use. Use a 0.4 A slow-blow fuse for

100/120 V ac;use a 0.2A slow-blow fuse for 220/240 V ac.

Trimmer for adjusting the internal reference oscillator.

@ INT. STD OUT./EXT. STD IN.

Internal reference oscillator and external reference signal selector switch.

INT. STD OUT. selects the internal reference oscillator and outputs the

GPIB connector is used to connect this unit to the GPIB interface for

externally controlling function, gate time/multiplier, hold of this unit.
