7. Impedance Test for pH

Testing a pH meter with simulated pH values only checks for the

accuracy

of the input circuit. It does not check for the

impedance

of the

input circuit. The input impedance must be extremely high to match the
pH sensor. If the input impedance has been reduced due to component
failure, corrosion etc, accuracy will be affected and the pH sensor may
suffer permanent damage.

To test the impedance of the pH meter’s input circuit…

1. Obtain the correct pH / mV output cable for the instrument under test.

2. Connect one end of the pH / mV output cable to the

WP-Sim

and the

other end to the instrument under test, as per the example diagram
below…

3. Switch the

WP-Sim

Function switch to ON. Switch the instrument

under test on and select pH mode. See the instrument’s handbook if
necessary.
