Description
The TPI SP670 Smart Pressure Probe is used to measure pressure 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 SP323 Smart Temperature Clamp Probe to calculate Superheat and Subcooling
using the App. The angled ¼´fitting allows access to service ports in close spaces.
The SP670 Schrader Valve Depressor is adjustable for use with worn valves in test ports. It can be
serviced as well to extend the life of the probe.
OPERATION
1.
Install the TPI View App on your smart device.
2.
Press and hold the SP670 on/off key for approximately 2 seconds to turn the smart probe on. An
orange LED will blink indicating the SP670 is ready to be paired.
3.
Open the View app and
tap ‘Start Scanning for TPI Smart Instruments’.
Tap on SP670 to
connect it to the app..
4.
The live reading will be displayed on the app. Units are selectable by tapping on the box next to
the live reading.
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 step 3 for the Liquid Line
connected smart probes.
4.
Tap on the refrigerant canister to select from favorites. Tapping on the gear also allows units of
measure to be changed as needed. The Pressure, Temperature and Vapor Saturation, and
Liquid Saturation will be displayed on the app.
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.
WARNING:
The SP670 reads up to 870 PSI and is overpressure protected to 1000 PSI.
Never apply more than 1000PSI as damage to the sensor may result.
