DESCRIPTION
The TPI SP323 Smart Temperature Clamp Probe is used to measure temperature on refrigeration
systems. It connects to a smart device using the TPI View App. It sends live measurement data and
can be used in conjunction with the SP670 Smart Pressure Probe to calculate Superheat and
Subcooling using the App. The SP323 is also capable of logging temperature measurements over time
to help identify intermittent problems.
OPERATION
1.
Install the TPI View App on your smart device.
2.
Press and hold the SP323 on/off key for approximately 2 seconds to turn the smart probe on. An
orange LED will blink indicating the SP323 is ready to be paired.
3.
Open the View app and
tap ‘Start Scanning for TPI Smart Instruments’.
Tap on SP323 to
connect it to the app.
4.
The live reading will be displayed on the app. Units are selectable by tapping on the live reading.
From here a differential measurement can be made using two SP323 or logging can be
activated. (See later in the manual)
SUPERHEAT & SUB-COOLING
Connecting two
SP670’s and two SP323 smart temperature clamps allow superheat and sub
-cooling to
be calculated.
1.
Turn on each SP670 and SP323, open the app and allow the smart probes to connect.
2.
Connect the probes to the Suction (low side) and Liquid (high side) lines.
3.
Tap on ‘Refrigeration’ in the app. For the Suction Line tap on ‘Pressure Select’ to assign the
SP670 connected to the suction line from the available devices. Repeat this for the ‘Temp
Select’ to assign the SP323 connected to the suction line. Repeat ste
p 3 for the Liquid Line
connected smart probes.
4.
Tap on the refrigerant canister to select the refrigerant being used. The Pressure, Temperature
and Vapor Saturation, and Liquid Saturation will be displayed on the app.
WARNING:
The SP323 reads up to 185°F, do not attach the probe to a device with
a temperature above this.
IMPORTANT:
When connecting the SP670 to a test port do not use the body of the
instrument to tighten the connection. Only turn the knurled knob of the smart probe. Using the
body of the instrument can result in damage to the SP670. Do not overtighten when
connecting to the test port or damage to the SP670 and port may result.
