Operation   Brochure

The PORTAPROBEII is a 4-in 1 digital portable tester/simulator for use with all CHEMTROL® controllers. As a tester, it reads signals from ORP, pH, conductivity and temperature sensors - independently from the controller. As a simulator, it generates sensor signals that can be used to verify proper operation of the controller.

Designed for easy field use, it features a 3 ½ inch LCD display, a 9 VDC battery power supply and all required connecting cables.

SIMPLE AND RELIABLE

 

The PORTAPROBEII (P/N PTS050) is a user-friendly and reliable tester/simulator that is designed to checkout and troubleshoot all CHEMTROL® controllers. It is covered by a full one-year electronics warranty.

 

 

SPECIFICATIONS

SENSOR TESTING

Set the Mode Switch to TEST (testing).

ORP SENSOR

Connect the ORP sensor to the left ORP BNC connector (above PROBES) on top of the PORTAPROBE . Turn the Selector Knob to ORP.

Place the sensor in balanced water (pH = 7.5 / PPM = 1.0 Cl). You should get an ORP reading within 650 to 750 mV.

Place the sensor in an acid solution. You should get a HIGH POSITIVE reading.

Place the sensor in a BLEACH (liquid chlorine) solution. You should get a LOW POSITIVE reading.

pH SENSOR

 

Connect the pH sensor to the left pH BNC connector (above PROBES) on top of the PORTAPROBE . Turn the Selector Knob to pH.

Place the sensor in nearly neutral water (pH = 7.5). You should get a pH reading of about -30 mV.

Place the sensor in an acid solution. You should get a HIGH POSITIVE reading.

Place the sensor in a BLEACH solution. You should get a HIGH NEGATIVE reading.

The linear scale on the right shows the conversion of millivolt readings into pH units.

TEMPERATURE SENSOR

Connect the sensor to the quick connector on the left side of the PORTAPROBE (PROBES). Turn the Selector Knob to TEMP. Place the sensor in ambient temperature water. You should be getting a correct temperature reading.

CONDUCTIVITY / TDS SENSOR

Connect the sensor to the quick connector on the left side of the PORTAPROBE (PROBES). Turn the Selector Knob to TDS. Place the sensor in tap water. You should be getting a reading between 500 and 1,000 ppm or mg/l.

Conductivity readings are automatically converted to TDS values, using a conversion factor of 0.5. For instance, a conductivity of 2,000 corresponds to a TDS value of 1,000 ppm or mg/l.

SIMULATIONSet the Mode Switch to SIM (simulation).

ORP AND pH SIMULATION

Before starting ORP and pH simulation, turn off the Probe Monitor option on the PC programmable controller.

Use the two coaxial cables to connect the BNC connectors (above SIMULATOR) on the top right of the PORTAPROBE to the respective BNC connectors on the controller.

Set the Selector Knob to either pH or ORP Simulator. The readings on the controller should match the readings of the simulator display (unless offset by calibration of the pH probe).

The outputs of the ORP and pH simulators can be adjusted with the two small knobs located below the digital display. The ORP range is 0 to 1,000 mV.. The pH range is -180 to + 180 mV (10 to 4 on the pH scale). These outputs can be used to test for proper operation of the feed and alarm features of the controller.

NOTE 1: Due to signal stabilization, the readings on the controller may take up to 10 seconds to reach full value.

NOTE 2: The ORP and pH signals can be simulated at the same time but only one signal is shown on the tester display.

TEMPERATURE AND TDS SIMULATION

Use the jumper wires to connect the quick connectors on the right side of the PORTAPROBE (SIMULATOR) to the temperature and conductivity inputs on the motherboard inside the controller.

The temperature simulator is set to simulate a fixed output of 80 OF (26.7 OC).

The conductivity simulator is set for a fixed output of 2,000 µSiemens or about 1,000 ppm (mg/l) of Total Dissolved Solids.
