The phrase, “rotary knob & <>”
is used in the following
explanation to instruct the user
to enter numerical setting values
using the knob and arrow keys.
For details on this procedure,
see section 3.7.
Arming must be set to external arming before carrying out the procedures in this
section. For the procedure to set arming, see section 4.6.
1.
Press SHIFT+INHIBIT (BLOCK). Block appears in Display 2, and the setting
value appears in Display 1.
2.
Use rotary knob & < > to set the number of blocks. If the number of blocks is
set to 2 or more, the BLOCK indicator illuminates.
Explanation
With block sampling, all data collected after performing one block of measurement a
specified number of repetitions is processed and displayed together. When using
external arming, you can set the number of block in the following range.
Setting range: 1 to 99 (in steps of 1 block)
Note
•
During normal measurement, the number of blocks is set to 1. For block sampling
measurements other than normal measurement, select a number of blocks of 2 or more.
•
The setting for the gate time and number of blocks is restricted such that maximum
number of samples that can be acquired by the instrument is not exceeded.
Conditional expressions
•
When D-to-C high speed calculation (see section 4.9) is OFF:
Gate time
×
no. of blocks
≤
5 seconds
•
When D-to-C high speed calculation is ON: Gate time
×
no. of blocks
≤
1 seconds

•
Once the gate time and number of blocks reaches the limit according to the condition
equation above, if the gate time is increased, the setting for the number of blocks is
automatically adjusted. For example, when D-to-C high speed calculation is OFF, and
when the gate time starts out at 50 ms and the number of blocks is 99, if the gate time
is increased to 500 ms, the number of blocks automatically changes to 10. However, if
the gate time is then returned to 50 ms, the number of blocks stays at 10.
•
If the gate time is decreased and the measurable number of blocks increases, the
setting for the number of blocks is not automatically increased. To manually increase
the number of blocks, perform the procedure described in this section.
