four decimal values ( 1 , 10, 100 and 1000 or
1 to 0.001). The measurement d a t a can be
displayed w i t h o u t decimal point while w i t h
up to t h i r d decimal place.
Note : In the frequency r a t i o measurement
mode, display unit select s w i t c h
( k H z / ^ s , M H z / m s ) © has no s i g n i f -
icance.
(5) The frequency r a t i o d a t a is output to the
D i s p l a y . G A T E L E D (D blinks during the
frequency r a t i o measurement.
The measurement value on the display w i l l
be updated a t the moment when one meas-
urement interval is complete (when the G A T E
L E D t u r n s o f f ) . The G A T E L E D blinking
may not be confirmed because it gets too
f a s t due to high-frequency signal measurement
on C H A N N E L B .
Note : The measurement m a y be delayed or
the output value display m a y be
unstable. In t h i s case, refer to section
5 - 6 ' D i s p l a y D e s c r i p t i o n ' .
(6) If H O L D s w i t c h © is turned on during
frequency r a t i o measurement, the current
measurement value on the D i s p l a y is held a s
it i s . If it is turned off, a new measurement
cycle w i l l be s t a r t e d . However, the measure-
ment value currently being displayed w i l l
remain unchanged until the new measurement
cycle is complete. T h a t i s , the display value
being held by the H O L D s w i t c h is updated
by the output value f r o m the new m e a s u r e -
ment operation.
(7) If R E S E T s w i t c h © is pressed during the
frequency r a t i o measurement, the measurement
value on the D i s p l a y w i l l be reset to ' 0 ' . If
pressed a g a i n , a new measurement cycle w i l l
be s t a r t e d . However, the measurement value
w i l l remain ' 0 ' until the new cycle is complete.
Note : If s i g n a l s are input to the counter
input jucks w i t h noise and ringing
superimposed on, refer to the item
'Input Adjustment F u n c t i o n s ' of the
preceding section, 'Frequency Measure-
