||||||||---- VL - Pump Current Sense Amplifier - 0 = x8, 1 = x17
|
|
If VL is set to "0" the amplification of Ip is 8.
|
|
If VL is "1" the amplification is 17. The higher
|
|
amplification is needed for a better resolution
|
|
at Lambda > 1, amplification 8 for Lambda < 1.
|
|
Note: It seems to make no difference, always set to 1.
|
|
|||||||----- Unused
|
|
||||||------ LA - Pump Current Sense Amplifier - 0 = measurement, 1 = calibration
|
|
If LA is "0" the measurement mode for Ip is active.
|
|
The current pump current is displayed on Ua. If LA is
|
|
set to "1" the calibration mode is active. The shown
|
|
voltage on Ua must been subtracted from the later measurement.
|
|
|||||------- Undocumented Bit - Note: CJ125 only seems to work when set to 1.
|
|
||||-------- RA - Measurement Current for Ri - 0 = measurement, 1 = calibration
|
|
If RA is "0" the measurement mode for Ri is active and
|
|
the current resistance of the probe is "displayed" on Ur.
|
|
If RA is "1" the calibration mode is active. You get the
|
|
optimal voltage for the inner resistance of the probe on Ur.
