The auto level control function of TH2826 can realize the measurement of constant voltage or
current. Auto level control function can be set as ON on <Measure> page. After the auto level
control function is on
,
“*” is displayed after the current level value. Detailed information,
please refer to<Measure> page.
Operational step of level setting
:
TH2826 has two kinds of level setting. One is using softkey
,
the other is using numeric key.
1
)
Move cursor to Level zone. The following softkeys will be displayed
↑
(+)
Press this key to increase the signal source output level.
↓
(-)
Press this key to decrease the signal source output level.
2
)
Use softkey or numeric key to select or set level. When using numeric key to input
the required level value
,
the available level unit (mV, V, µA, mA and A) are displayed,
which can be used to input unit and data. When using [ENTER] to input level
,
the
default unit is V or A.
