@ 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 m s/ 10 °
-*
0.1 s / 101 -> 1 s / 102 -*
10 s / 103
-*■
10 m s/ 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.
© STD ADJ.
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
frequency value at © . When EXT. STD IN. is selected, the external
reference signal fed to © operates this unit.
© Reference signal I/O connector. See © .
© GPIB connector
GPIB connector is used to connect this unit to the GPIB interface for
externally controlling function, gate time/multiplier, hold of this unit.
