Recording Accuracy
● Overview
Set the channels to the 2 V range and confirm that the recording accuracy is within
the criteria.
Pen Model
Check the accuracy of all pens. Use standard pens (or equivalent).
*A “standard pen” is one whose tip does not fluctuate more than ±0.1 mm.
Dot Model
Check an arbitrary channel.
● Recorder Settings
Set the input to the 2 V range, and −2.000 V to 2.000 V.
● Procedures
Input values equivalent to 0, 25, 50, 75, and 100%, and record.
Measure the recorded results using a Glass scale (or equivalent), then confirm that
the results meet the criteria below.
Criteria
Input Criteria
−2 V 0 ±0.5 mm
−1 V 45 ±0.5 mm
0 V 90 ±0.5 mm
1 V 135 ±0.5 mm
2 V 180 ±0.5 mm
Note
These criteria do not include the measurement accuracy. When taking the measurement
accuracy into account, the criteria are measurement accuracy ±0.5 mm.
Z-Fold Chart Paper Feed Accuracy
● Procedures
1. Turn ON the power switch while pressing the
MENU
and
CH UP
keys. Menu =
A/D Adjust is displayed.
2. Select Menu = Test, and press the
key.
3. Choose Test = Print and press the key.
4. Select Menu = Chart, and press the
key.
The recorder starts feeding paper, then stops after approximately 500 mm. Time
ticks are printed between the start and stop of paper feeding. Check that the
space between the two time ticks (d1 + d2 + d3 in the figure below) satisfies the
criterion below. Measure using a Glass scale (or equivalent).
Criterion: 500 ±0.4 mm
Time ticks
12.5 mm
d2 (Number of scale
intervals × 12.5 mm)
d3 (measured with
a Glass scale)
d1 (measured with
a Glass scale)
* Select using the key. You can hold down the SHIFT key while pressing key to reverse the
key’s action.
