HST Measurement
3.1.
Measurement
When powered on, the SP-395 will be in the measurement (read) mode (see figure 3). The displayed
value is the concentration of HST.
The light shield should be in the closed position in order to measure HST. If only conductivity is
measured, the light shield can be left in the open position.
