/**********************************************************************************
INIT_REG1 - CJ125 Initialization Register 1
00x000x0
||||||||---- 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.
|||--------- Unused
||---------- PA - Pump Current Control - Set to 0 to be active
|----------- ENABLE/HOLD - Must be set to 1 to enable
