1. Instrument test ORP
1 - Connect
Connect the PH-T via the adapter to the ORP cable of your instrument.
2 - Switch on
Switch on the PH-T by pressing key “ON“ for 5 seconds.
NOTE
Switch-on is delayed to prevent accidental activation during transport.
3 - Test
Test in progress - if your instrument is working fine, it displays now the same value that
is shown in the display of the PH-T.
By use of the scroll keys of the PH-T you can set an arbitrary value /-1500mV.
Your instrument must react within a few seconds to any changes and finally show the
same value as the PH-T.
NOTE
If you press a scroll key once, the value increases or decreases by 1 .
Hold it, and the value starts changing continuously, first slowly, then
faster.
