Instrument Description
The Model APC ErgoTouch Pro 2 has many features to make measurements convenient.
They are described in detail below.
Using the Instrument Stand and Stylus
The Model APC ErgoTouch Pro 2 is equipped with an
integral instrument support stand. To open the stand,
grasp it by the large finger hole and pull it out until it
locks into place. Be careful not to overextend the stand.
To store the stand out of the way when not in use,
simply push the stand back until it snaps into place.
The Model APC ErgoTouch Pro 2 is also equipped with
a plastic stylus for use with the touch screen interface.
The stylus locks into place in the case near the top of
the unit when not in use.

Providing Power
The Model APC ErgoTouch Pro 2 may be powered using a rechargeable lithium-ion
battery, or through an AC power cord.
NOTES
•When using AC power, the battery (if installed) charges when the instrument
is on, but not while actively sampling.
•Removing/changing the lithium-ion battery or disconnecting AC power does
not cause loss of data.
To Install the Lithium-Ion Battery
1. Remove the battery cover from the back of the instrument by lightly depressing
the textured tab on the cover located on the lower left.
2. Place the lithium-ion battery into the battery compartment and slide it forward
(toward the top of the unit) until it locks into place.
3. Replace the battery cover and slide it in place until you hear a click.
WARNING
The battery supplied has built in protection against explosion
and fire hazard. Do not use a substitute.
WARNING
Do not use non-rechargeable batteries in this instrument.
Fire, explosions, injury or other hazards may result.
To Use AC Power
1. Connect the AC power adapter to the power cord.
2. Insert the AC power adapter into the side of the Model APC ErgoTouch Pro 2
3. Connect the power cord to an outlet.
4. Press the on/off button (located on the front of the instrument handle).
5. After a splash screen displays the logo, a brief start-up sequence begins as
the Windows® CE operating system boots up.

9
Using with a Printer
A hard copy of a sample set can be printed
from the instrument using the optional
Model 1.44163.0001 thermal printer
(see Chapter 3, “Operation”). Only the Model
1.44305.0001 printer is compatible with
the Model APC ErgoTouch Pro 2.
The printer may be used on its internal
battery or an AC adapter. A custom commu-
nications cable is included with the printer.
The cable goes between the USB A port and
the 9 pin DSUB on the printer.
•
•
Performing a Zero Check
A zero check should be performed at least once a day. It should also be performed
before conducting any important testing or certification.
To Perform a Zero Check
1. Turn on the instrument and wait until the main menu appears.
2. Remove the Isokinetic inlet if attached. The zero check cannot be performed when
the isokinetic inlet is attached to the instrument.
3. Attach the zero filter to the inlet nozzle
located on the top of the instrument.
4. Press the Start button and allow the instrument to purge for 2 minutes.
5. After the 2-minute purge, continue to sample. In accordance with JIS standards,
there should be no more than 1 particle counted at any size in 5 minutes.
NOTE
If the instrument does not go to zero (1 particle in 5 minutes is considered
zero), refer to Chapter 6, Troubleshooting, for additional information.
6. Remove the zero filter and put the isokinetic inlet back on—the instrument is now
ready for operation.

10
Installing an Isokinetic Inlet
The Isokinetic inlet smoothly accelerates air
into the inlet of the instrument. To install,
simply thread the inlet directly onto the inlet
nozzle until finger tight. The inlet seals over
an O-ring so it doesn’t have to be very tight
to seal.
Installing a Temperature/Relative Humidity Probe
To install the optional temperature/relative humidity probe:
1. Align the probe so the pins slide into the sockets of the base connector.
2. Align the locking collar on the probe so it will slide over the alignment pins
on the base connector
3. Press down and turn the locking collar to lock in the probe.
4. Temperature and relative humidity are automatically displayed in the
upper-left corner.
5. Remove the probe turned the locking collar
and then pulling straight up on the probe.

11
3 Operation
The Model APC ErgoTouch Pro 2 Handheld Airborne Particle Counter is controlled using a touch screen display.
Use the plastic stylus or your finger tip. DO NOT use sharp objects (such as a pen point) that may damage the
screen overlay.
To turn on the instrument, press the on/off button
(located in the center of the front of the instrument).
After a splash screen displays the logo, a brief start-up
sequence begins as the Windows® CE operating system
boots up.
The instrument is ready for operation when the main
tab shown on the side appears. If an optional tem-
perature/humidity probe is attached, those values will
be shown in the upper-left corner also.
Screen Layout and Functionality
There are four main screens (tabs): Main, Setup, Data, and Reports. The operation of each of these screens, the

communication between its nodes.
Subnet Mask A network of computers and devices that have a common, designated IP address
routing prefix. All hosts within a subnet can be reached in one “hop” (time to
live = 1), implying that all hosts in a subnet are connected to the same link.
Default Gateway A node on the computer network that serves as an access point to another net-
work and is chosen when the IP address does not belong to any other entities in
the Routing Table.
Use DHCP (Dynamic Host
Configuration Protocol)
When checked, this protocol is used to automatically obtain the information
necessary for operation from a DHCP server running on your local network.
NOTE
TCP/IP is an industry standard networking protocol that allows computers and devices to communicate
over Ethernet and other media access channels. Providing full details on how to configure an IP network
is beyond the scope of this manual. Please contact your company IT department or a qualified network-
ing professional if you are not qualified to configure such a network.

Field Description
Sample Sample is the total number of samples you want collected. In Automatic mode, a Count value of
0 causes the instrument to count continuously using the settings for Delay, Time, and Hold until
the Start/Stop button is pressed again. Use the up and down arrows or the on-screen keyboard
to set the count. See Count Mode Screen for information on the different count modes.
Delay Delay indicates how long it will be before the first sample is taken. Remember, it takes approxi-
mately 6 seconds for the pump to reach the flow set point; taking a measurement before the
pump is functioning properly may result in a data error.

channel. Press OK when finished.
Field Description
Enable Select the channels on which you want to enable alarms.
Threshold To change the threshold for any channel, click the up and down arrows for that channel or use
the on-screen keyboard to change its value. The threshold value units use the current display
Count Units (see Count Units Screen).
