t6 EOM Output pulse width When the external trigger is selected
HOLD setting : Holds until the next trigger is detected
PULSE setting : Remains only for the specified pulse width
See " Instrument Settings" (p.84).
When the internal trigger is selected
HOLD setting : EX.FAST 1 ms, FAST 5 ms, MEDIUM 20 ms (50 Hz line
frequency setting)/ 16 ms (60 Hz line frequency setting), SLOW 50 ms
PULSE setting : Remains only for the specified pulse width

: About t4 measurement time
When averaging is enabled, the running average is obtained with internal triggering, so measurement time
t4 does not change. The measurement time for external triggering is as follows:
With SLOW sampling
V (t4 - 57.8) × n + 57.8 ms (50 Hz)
(t4 - 51.2) × n + 51.2 ms (60 Hz)
or V (t4 - 56.4) × n + 56.4 ms (50 Hz)
(t4 - 49.8) × n + 49.8 ms (60 Hz)
With other than SLOW sampling
V (t4 - 2.8) × n + 2.8 ms
or V (t4 - 1.4) × n + 1.4 ms
(n represents the number of values averaged)
*3
: About t5 calculation time
In the following cases, add the indicated times to calculation time t5:
When the Statistical Calculation function is enabled 0.3 ms
When the reference value/tolerance method of
comparator decision is selected
0.15 ms
