Probe connections
See Figure 9 .
Your meter includes two probes:
• pH electrode with BNC connector
• conductivity/TDS/temperature probe with a notched
6-pin connector
The temperature sensing element built into the conductiv-
ity/TDS probe will also compensate for pH readings as long
as both probes are in your solution at the same time.
If you want to use an “All in One” pH probe with a built-in
temperature element, or if you want to use a separate
temperature probe, you will need to disconnect the
conductivity/TDS probe to allow for connection of the
separate temperature sensor.
You can use any standard pH, mV (ORP) or Ion Selective
electrode with a BNC connector with this meter.
Conductivity/TDS probes, “All in One” pH electrodes with a
built-in temperature element, and separate temperature
probes require a probe with a notched 6-pin connector.
For replacement probes, see the “Accessories” section,
page 43.
To connect the pH electrode:
1.
Slide the BNC connector of the probe over the BNC
connector socket on the meter. Make sure the slots of
the connector are in line with the posts of the socket.
Rotate and push the connector clockwise until it locks.
2.
To remove probe, push and rotate the connector
counterclockwise. While holding onto the metal part of
the connector, pull probe away from the meter.
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.
2.
To remove probe, turn locking ring counterclockwise on
the probe connector. Pull probe away from the meter.
NOTE: follow the same directions to connect an optional sep-
arate temperature element.
Power connections
See Figure 9 .
Your meter includes an AC to DC adapter:
To connect the AC adapter:
1.
Slide the phono plug of the AC adapter into the “DC” slot
on the back of the meter.
Attention!
Do not get water on the connectors
during operation. A
void touching
the connector with soiled or wet
hands. Do not pull on the probe
cord or the probe wires might
disconnect.
