The operation level offers two mode categories: the measurement and calibration operation
modes.
Note that the function for which you have set a data value at the setting level does not work at
all if that function is turned off at another level. For this reason, care must be taken when dealing
with modes that relate to each other.
This subsection explains the operating procedures for the levels/modes noted below.
The calibration operation mode is discussed in Chapter 8.
(1) Operation level
(2) Display mode (DISP mode)
(1) Operation Level
Select a mode from the following four choices of the operation level. Each press of the [NO] key
cycles through the choices in the order shown below:
1. Display mode [DISP]
2. Semi-automatic calibration mode [SEM.CAL]
3. Manual calibration mode [MAN.CAL]
4. Valve operation mode [VALVE]
Press the [YES] key to enter the desired mode when it is indicated.
