98Probe informationYour AP85 meter includes two probes:• single junction, epoxy body combination pH electrode with BNC connector• conductivity/TDS/temperature probe with a notched 6-pin connectorThe temperature sensing element built into the conductivity probe will alsocompensate for pH readings as long as both probes are in your solution at thesame time.If you want to use an “All in One” pH probe with a built-in temperature element, orif you want to use a separate temperature probe, you will need to disconnect theconductivity/TDS probe to allow for connection of the separate temperature sensor.You can use any standard pH electrode with a BNC connector with this meter.Conductivity/TDS probes, “All in One” pH electrodes with a built-in temperatureelement, and temperature probes require a notched 6-pin connector.NOTE: Keep connector dry and clean. Do not touch connector with soiled hands.3.2 To connect the pH electrode:1. Slide the BNC connector of the probe over the BNC connector socket on themeter. Make sure the slots of the connector are in line with the posts of thesocket. Rotate and push the connector clockwise until it locks.See figure below.2. To remove probe, push and rotate the connector counterclockwise. Whileholding onto the metal part of the connector, pull probe away from the meter.CAUTION: Do not pull on the probe cord or the probe wires might disconnect.To connect the conductivity/TDS/temperature probe:1. Line up the notch and 6 pins on the meter with the holes in the 6-pin connector.Push down and turn the locking ring clockwise to lock into place.See figure below.2. To remove probe, turn the locking ring counterclockwise on the probe connector.Pull probe away from the meter.NOTE: follow the same directions to connect an optional separate temperatureelement.CAUTION: Do not pull on the probe cord or the probe wires might disconnect.conductivity/TDS temperature probe(with 6-pin connector)locking ringpH electrode(with BNC connector)top view of 6-pinconnector—conductivity/TDStemperature probe
