4 Operating

Procedure

The simulator is designed to test the accuracy of your pH/ORP meters. It includes the
simulation values for the USA and NIST buffer set standards and the simulation
performance of an electrode in pH 4.01 and pH 10.01 buffers (4 Hi Z & 10 Hi Z). This
High Impedance pH simulation is useful for testing suspected leakage problems of your
pH/ORP meters.

1.

Connect the BNC end connector of your simulator to the pH/ORP meter.

2. Switch the simulator on by pressing the ON/OFF button. The ‘7.00’ LED will

light up indicating that the pH 7.00 simulation value has been selected.

Note: The simulator will always be in the pH 7.00 selection every time it is turned
on

.

3. Press

the

▲ and ▼ key to scroll through the value selection on the LED

display. The LED will light up according to your preferred selection.

4.

Select the desired simulation value indicated by the LED light up display.
