Set the measurement level according to the parameter. When setting is done the 889B will return “OK” string.
PARAMETER:
ASCII string Numerical code
1VDC 0
1Vrms 1
250mVrms 2
50mVrms 3
Example:
LEV 1V
OK
 LEV?
Return the current measurement level setting.
Example:
ASC ON
OK
LEV?
1Vrms (return value)
ASC OFF
OK
LEV?
1 (return value)
MODE?
Query the measurement mode. If in LCR measurement mode, six fields will be returned.
1. Frequency
2. Level
3. Measurement mode
4. Unit of primary display
5. Unit of secondary display
The existence of field 5 depends on the measurement mode. For example, there’s no field 5 if the measurement
mode is DCR. The separation between fields is space (ASCII 20H).
Example:
ASC ON
OK
CPD
OK
MODE?
1KHz 1Vrms CpD uF (return value)
ASC ON
OK
CPRP
OK
MODE?
1KHz 1Vrms CpRp uF Ohm (return value)
If in Voltage measurement mode, three fields will be returned.
1. Measurement mode
2. Unit of primary display
