Sample Report (Brief)
IB mV (Initial Baseline Voltage). The initial baseline voltage is monitored before a sample or calibration. The IB voltage
must be stable and between -40 and 60 mV.
NPL mV (Net Plateau Voltage). This is the peak voltage minus the baseline voltage.
xNPL nA (cross Net Plateau Current). Net plateau current of the other sensor in the module.
PL Slope (Plateau Slope). The slope is reported in mV per minute. An excessive slope can be an indicator of ISE
problems.
Avg (Average). The average PL voltage for the calibration sequence (last 3 cycles of each calibrator).
Std Dv (Standard Deviation). The standard deviation of the PL voltage for the calibration sequence (last 3 cycles of each
calibrator). Must be less than 0.2.
->Coef (Selectivity Coefficient). The response of the ISE to one calibrator vs. the other calibrator. Calculated during the
last 3 cycles of each calibrator. Must be greater than zero and less than 0.3 for ammonium; greater than zero and less
than 0.1 for potassium. Depending on the application, the 2950 may operate with an ammonium coefficient as high as
0.40, provided it passes the daily checks in section 5.1. However, it is the user’s responsibility to determine if operation is
acceptable for their specific application.
->Slp (Slope). The response of the ISE in mV per decade over the range of calibrator solutions. Must be greater than 52
mV/decade.
