Oakton 1000 1/4 DIN pH/ORP controller Operating instructions

Below you will find brief information for pH/ORP controller 1000 1/4 DIN. This is a microprocessor-based pH/ORP controller that can be used to measure either pH or ORP with proportional or on/off control. You can use the controller in panel mounted enclosures. This controller has many user-friendly features, including a menu-driven program that simplifies set-up, a large dual display LCD shows pH (ORP) and temperature along with clear multiple annunciators, two set point, two SPDT relay operation, three control modes, 0 to 2000 second time delay adjustment on all relays, a separate alarm relay alerts you to set points exceeded for a specific length of time or a failed temperature sensor, separately adjustable high and low set point hysteresis bands, 0-20/4-20 mA transmitter/recorder output, protection against electromagnetic interference, push button two-point calibration and electrode offset adjustment, easy, fast calibration with auto buffer recognition, nonvolatile memory maintains setup even when power fails, two level password protection, and LED indicators signal control activities to monitor controller status from a distance.

Frequently asked questions

You need to enter a security code. This controller features two levels of security codes to protect the numerical values, calibration data and unit parameters from unintentional alteration.

The HOLD function lets you force the relays to their resting position by applying a contact closure across terminals 13 and 14. When the HOLD function is activated, the HOLD indicator will appear in the upper left corner of the display.

The LED indicators provide a quick way to check controller status. They show whether a parameter within its set limits (green light) or outside its set limits (red light).

Enter Calibration mode, place the sensor in the calibration solution, press the ENTER key, determine the mV value of your solution with a meter known to be accurate, press the ▲ and ▼ keys to offset the mV value on the controller display to match the value of the solution you are measuring, and press the ENTER key to return to Measurement mode.
