1 INSTALLATION QUALIFICATION
1.1 REQUIREMENTS
NOTE: High ambient temperatures may create instability in the readings.
The 2H requires the following for proper operation:
• Stable electrical power at 90/240 VAC, single phase, 50/60 Hz, 5 amps.
• Environment Operating Range: 35° to105° Fahrenheit (1.6° to 40.6° Celsius)
with less than 75% relative humidity.
1.2 UNPACKING
NOTE: Save all packaging material for future use.
Carefully unpack and remove the 2H Aerosol Photometer and all accessories from its shipping
container. If the instrument has been damaged in transit, notify the shipper immediately.
Make sure the following items are included with both the 2H (9300133) and the 2HHP (9300134):
1) 1 power cord, 6700001 (120 VAC) or T2E0-0063 (220 VAC)
2) 12 feet of clear PVC tubing, 5200116
3) Operating Manual, 1800110
4) Calibration certificate
The following items are optional. Check the order packing slip.
1) Shipping case, 9300145
2) 2H-SP Scanning Probe, complete, 9300144
a) 1 round isokinetic nozzle (red), T2E0-0572
b) 1 rectangular isokinetic nozzle (blue), T2E0-0798
c) 1 NSF 1” round nozzle (black), T2E0-0005
d) 1 Scanning probe, T2SP-0881
If any of these items are on the order packing slip but missing from the shipment, contact ATI
immediately at:

Figure 1. Front View
1. Selector Valve. Selects the sample source.
2. Upstream Sample Port. Connects to the sample tubing that is used to measure the upstream
aerosol concentration.
3. Scanning Probe Ground Jack. Electrical ground connection for scanning probe shielding.
(Required for CE compliance)
4. Scanning Probe Connector. Electrical connection for the optional Scanning Probe.
NOTE: Connect the Scanning Probe before applying power to the 2H. Failure to do so
will result in the lack of operation of Scanning Probe’s display. If this occurs, simply
turn off the power to the unit and restart the system.
5. Downstream Sample Port. Connects to the sample tubing or optional Scanning Probe that is
used to measure the downstream sample.
6. Optics indicator light. Corresponds to the cleanliness of the optics.
Green Light Less than 10,000mg* of aerosol
has moved through the
scattering chamber.
Orange Light More than 10,000mg* but less

than 17,000mg* of aerosol has
moved through the scattering
chamber.
Red Light More than 17,000mg* of aerosol
has moved through the
scattering chamber. Servicing of
the unit is highly recommended.
* Note: These values are approximate. Actual mass may vary with different airflow rates and
aerosols.
7. Flow indicator light. Displays green when flow is within 5% of 1 CFM, yellow when flow is
from 5% to 10% of 1 CFM, and red when flow is more than 10% above or below 1 CFM.
8. Function Keys. Used for setting operating parameters and initiating program routines
9. Bar Graph Display. Displays an analog representation of the % leakage to aid in isolating
leaks.
10. Front Panel Display. Indicates % leakage readings and error messages.
2.2 FRONT PANEL CONTROLS AND INDICATORS
The front panel contains seven pressure-activated function keys. The <0>, <100>, <REF>, and
<ALARM> keys each contain a red LED to indicate the state of the switch or to prompt the
operator. The <Δ> and <∇> keys are used to scroll among selections as they are shown on the %
LEAKAGE display. The <ENTER> key serves as the command key for sending information to
the processor and for initiating or stopping system routines. The <Δ>, <∇>, and <ENTER> keys
contain no indicator LED.
The % LEAKAGE display is an array of high-visibility LEDs that forms a display screen. The
Front Panel Display shows alphanumeric messages. Below it is a Bar Graph Display that gives a
visual indication of internal photometer cycling or an analog representation of quantity or
percentage.
The Scanning Probe contains an unlabeled display on the pistol grip that is a half-scale duplicate
of the % LEAKAGE Indicator. The two displays are driven by the same electronics and will
always read exactly the same.
The Selector Valve, the Scanning Probe connector, and the two barbed fittings are discussed later.
2.3 SCANNING PROBE CONNECTIONS
If using the 2H with the Scanning Probe, connect the probe’s electrical connector to the 12-pin
connector on the front panel of the 2H before applying power to the photometer. Otherwise, the
display on the Scanning Probe will not function. Connect the probe’s sampling hose to the barbed
DOWNSTREAM fitting to the right of the 12-pin connector. The cable and sampling hose are

bound as a single, flexible umbilical. Select the appropriate probe nozzle and screw it onto the
threaded end of the flexible portion of the Scanning Probe.
Note: When using the TDA-2SP Scanning Probe with the 2H, the probe must be
connected to the photometer before the power is turned on. Otherwise the 2H will not
detect the probe and no display will be observed on the pistol grip. If this occurs, switch
the power off, verify that the probe is connected properly, and then switch the power back
on.
