Set Up
Supplying Power to the Instrument
These instruments can be powered with a battery or with the AC adapter.
Installing the Battery
Insert the battery as indicated by the diagram located on the inside of the
battery compartment. The Lithium-ion battery is a rechargeable battery. When
a new battery is fully charged and used in the AP500, it will last for more than
8 hours at 100 ft/min (0.5 m/s) and 77°F (25°C). Runtime will be shortened at
colder temperatures and higher flows. With Model AP800 new fully charged
batteries typically last more than 32 hours.
Use only the AC adapter provided (TSI part number 800531) and do not
substitute another adapter or use a computer to supply power. Use of an
incorrect power supply can cause the measurements to be inaccurate.
Note
The battery must be installed before the AC/DC adapter is plugged in to
initiate recharging. If the AC/DC adapter is plugged in before the battery is
installed then the battery will not recharge.
Using the AC Adapter
The AC adapter can be used to power the instrument and to charge the
battery. Be sure to provide the correct voltage and frequency, which is
marked on the back of the AC adapter. When the battery needs to be
recharged, plug in the AC/DC adapter. Observe the orange LED which
indicates the battery is in the process of charging. The LED will turn off once
the battery is completely charged.
Using a Memory Card
The instrument allows for the use of a micro SDHC card to provide additional
data storage. The memory card must be purchased separately. It must be
preformatted with a FAT32 file system with a minimum of 100 MB space free.
The memory card plugs into the slot next to the USB port.
DO NOT use more than 3 feet of extensions or the measurement will become
inaccurate.
Note
For temperature and humidity measurements, make certain that at least
3 inches (7.5 cm) of the probe is in the flow. This will allow the temperature
and humidity sensors to be in the air stream.
Connecting Probes
The probes for the Model AP500 instrument screw into the top of the handle.
Insert the probe into the knurled nut and hold it tight. Then twist the knurled
nut until tight. It should take only 5 to 6 turns and a hard stop will indicate
when it is tight. You can orient the probe 360 degrees by loosening the nut,
twisting the probe and retightening the nut. The probe for Model AP800 is
integrated into the instrument and is not removable.
Using Extensions
Extensions can be used to extend the reach of the probe by up to 3 feet.
Using Locator Clips
Locator clips snap onto the probes and slide easily along the probe body.
They are used to set the depth at which the probe is to be inserted into an
airstream.
DO NOT expose the pressure ports to more than 190 inH
2
O (47280 Pa)
pressure differential. This will damage the sensor and make the measurement
inaccurate.
The Model AP800 can
be used with the Static
Pressure probe by
connecting to the
“+” port on the
instrument using
pressure tubing. The
Static Pressure probe is
used to measure the
duct static pressure and
features a magnet which
holds the probe to the
ductwork.
Using the Pressure Ports (Model AP800 only)
The Model AP800 has pressure ports that can be used to measure static and
differential pressures. The “+” port connects to the higher pressure and the “-”
port connects to the lower pressure. When the pressure is connected the
same way the tubes are marked, the meter displays a positive number. When
the pressure is reversed, the meter displays a negative number.
The pitot velocity needs a valid temperature to perform the standard or
actual velocity correction. The temperature setting is controlled in the AirPro
Mobile application, see Chapter 4.
Total pressure hole
Static pressure holes
Static pressure port
connects to “-” input on
instrument.
Total pressure port
connects to “+” input on
instrument.
Connecting an Optional Pit o t Probe
When connected to a pitot probe, air velocity or air volume can be measured.
A pitot probe can be connected to the “+” and “-” pressure ports on the Model
AP800 using two pieces of tubing of equal length. The total pressure port of
the pitot probe connects to the “+” port on the instrument, and the static
pressure port of the pitot probe connects to the “-” port on the instrument.
The carrying cases can be used to store and transport the instruments,
probes and accessories. The small case accommodates one instrument and
one probe while the larger case accommodates two instruments and two
probes. The probe protective case will accommodate any of the probe
variants. Use the protective probe case to transport and store the probe when
it is not in operation.
