TPI 600 Series User manual

Introduction
Congratulations
Thank you for purchasing TPI brand products. This meter is easy to use and is built to
last. It is backed by a 3 year limited warranty. Please remember to return you product
warranty registration card.
Product Description
The TPI 600 series is a hand held range of pressure meters and can be summarized as
follows.
TPI 610 - Single Input - 4 Function - single unit of pressure
TPI 615 - Single Input - 7 Function - 7 units of pressure
TPI 620 –Dual Input –differential –4 Function –single unit of pressure
TPI 625 –Dual Input –differential –7 Function –7 units of pressure
All these models measure over the range of -200.0 to +200.0 mbar. Each unit has
increased resolution of 0.01 mbar and automatically auto-ranges at + 19.00 mbar to 0.1
mbar resolution. Each model is supplied complete with carry pouch, battery and
instruction manual.

Safety Considerations
Warning: Please follow the manufacturer’s test procedure whenever possible. Make
sure the pressure to be measured is not outside the range of the TPI 610/615/620/625
meter
General Guidelines
Always
·Test the pressure meter before use to ensure it is operation properly
·Ensure that the connection hose you are using is free from kinks or splits
·Double check all connections before testing
Never
·Connect the Instrument to an unknown pressure source if the source is twice the
working pressure of the instrument the sensor will be damaged and may cause
injury to the user
·Tamper with the instrument or attempt to modify it in any way. Otherwise
accident and injury may occur and the warranty becomes void.

Features & Benefits
Autoranging - Provides high resolution & accuracy at low pressures where it is needed
Auto Power Off - Powers off after 40 minutes to conserve battery life.
Trim Mode - Smoothing function to stabilize erratic readings. It displays the average
value of 4 values previously measured.
Zero Function - Provide immediate push-button zeroing for Speed and accuracy.
Record Max/Min- Enables long term testing of pressure circuit to check for leaks.
(TPI 615/625 only)
Hold- Enables the user to freeze the display reading when working in cramped working
conditions, when the display is not visible. (TPI 615/625 only)
Units- Change the display value in any one of the following engineering units. kPs, PSI,
inHg, mmHg, inH20, mmH20 and mbar. (TPI 615/625 only)

Step by Step Procedures
·Press the ‘ON’Key and the LCD display will be activated if it does not read 0.00
proceed as follows
·Press the ‘ZERO’key and the display should zero within +/- 0.05 if not repeat
until it does
·Connect pressure meter to installation or equipment to be tested using appropriate
hose connection in accordance with the manufacturers instructions
·The pressure reading will appear on the display. To activate the backlight in poor
light conditions press the ‘ON’key at any time
·If the reading is erratic or changing activate the smoothing function by pressing
the ‘=’key
·To freeze a reading in awkward or cramped working spaces press the ‘HOLD’
key (TPI 615/625 only)
·To record maximum & minimum pressures when establishing pressure decay or
carrying out gas line soundness testing press the ‘MAX/MIN’key (TPI 615/625
only)
·To convert the displayed pressure reading to another engineering unit depress the
‘UNIT’key anytime and scroll through to the desired units of pressure. (TPI
615/625 only)
