App
Index
• Range > Unit
Set the unit (up to 6 characters,
A a # 1
).
• Alarm
For details on items other than those listed below, see section 3.7, “Setting Alarms on
Channels.”
•
Alarm > Type
The alarm types that you can select from are high limit alarm (H), low limit alarm (L),
delay high limit alarm (T), and delay low limit alarm (t).
• Alarm > Value
Set the alarm value by specifying the mantissa and exponent. The range is 1.00E–16
to 1.00E+16. Set the mantissas to values in the range of 1.00 to 9.99.
Note
• If you set the number of mantissa display digits to 2, the second decimal place of the
mantissa will be ignored. When you set the number of mantissa display digits to 2, set the
second decimal place of the mantissa of the alarm value to 0.
Example: If you set the alarm value to “1.56E+12,” the actual value will be “1.5E+12.”
• The alarm hysteresis on channels that are set to log scale is fixed to 0%. The alarm
hysteresis setting (see section 3.5) is not applied to channels that are set to log scale.
• Color Scale Band
For details on items other than those listed below, see section 5.8, “Displaying Alarm
Point Marks and Color Scale Band on the Scale.”
•
Display Position > Lower and Upper
Set the display position by specifying the mantissas and exponents. The range is
1.00E–16 to 1.00E+16. Set the mantissas to values in the range of 1.00 to 9.99.
Set the settings so that Lower is less than Upper.
• Display digits > Digits
You can set the number of digits in the mantissa of digital values to 2 or 3.
Example: If the number of mantissa display digits is 2, “1.2E+02.” If the number of
mantissa display digits is 3, “1.23E+02.”
This setting also affects the alarm values in the alarm settings. See the Note under
“Alarm” above.
• Input > LOG
You can select the LogType2 from Linear or Pseudo.
Linear: Sets a log linear input to LogType2 mode in the range setting.
Pseudo: Sets a pseudo log input to LogType2 mode in the range setting.
This setting applies to all channels.
