7.2.4 Parameter Setting at Service Level
To move to the service level, select [*SERVC] at the setting level, and press the [YES] key.
(see Figure 7.4 on page 7-10.) The main task at the setting level is to set data values such as a
measuring range. To go into each mode of the service level, enter the appropriate code number.
CAUTION
DO NOT enter codes other than those listed in Table 7.4. A change to the settings of any
unlisted code can result in the failure of the analyzer to operate properly. If you have entered
a wrong code number by mistake, press the [MODE] key to return to the measurement
mode(<MEASURE>). You may exit the mode of that wrong code by pressing the [ENT] key, if
you haven't made any change to the relevant data.
When [

[YES] key. The message field changes to look
like the one shown left.
Press the [ENT] key with code number 01 shown

the mode for setting the parameters of that code.
