1. Device Overview
Figure 1.1
An overview of the front face of the EIC micromanometer
is given in Figure 1.1. The front face includes:
●Advertising Name – it shows up in the scan list;
●OLED screen – displa screens: live or an average of
10 seconds pressure readings in unit of Pascal or
inH2O, and device information;
●Detector Type & Mac address — if ou need to
connect to our app for remote monitoring, find and
choose the device with this name and address;
3
●Port 1 & 2 – the manometer measures the pressure
differences between these two ports;
●Button – control device to turn on and off, to toggle
OLED screens and to manuall set zeros;
●Operation Stic er – indicates button operations.

2. Basic Operation
Basic operation of the EIC manometer is outlined in the
following steps:
1) There should 2 new AA batteries in the device when
ou receive the manometer. The manometer should be
in sleep mode. To start the manometer, press and hold
the button (for more than 3 seconds) until OLED
starts displa ingNote(i). You can release the button once
the OLED shows “Measuring..”. After displa ing
“Measuring” for 3 seconds, it shows “LIVE” screen.
“LIVE” screen readings are the average readings of 1
seconds. See Section 3 “OLED Screen Overview” for
screen interpretation.
2) Short pressing the button (for less than 2 seconds)
toggles screens. There are three screen displa s and
the are in the order of:
(a) Live readings (average of 1 second)
(b) Average readings (average of 10 seconds b
default. This can be modified through the app)
(c) Device information (Name, Mac address, batter
percentage and temperature)
The screen toggles from (a) to (c) and then back to (a)
again. The OLED screens updates ever second.
3) When ou press and hold the button for more than 2
seconds, the OLED starts displa ing instructions. You
5
can follow the instructions on the OLED. ES008-M
and ES008-MXS have different button operations:
Button Press
Time:
ES008-M ES008-MXS
Short (<2s) Toggle Screens
Long (2~5s) “Release to Zero” “Release to Shunt
Down”
Extra Long (>5s) “Release to Shunt
Down”
“Release to Zero”
When the OLED shows “Release to Zero”, it means if
ou release the button now, the manometer will
displa “Zeroing” and it storesNote(ii) the pressure
reading at that point as the new “zero point”/offset. It
will then go back to the displa screen before this
button operation.
When the OLED displa s “Release to Shut Down”
and ou release the button then, the device will
displa “Shunting Down” and it starts the shunt down
process. The OLED will be off after 3 seconds and
then the manometer will enter sleep mode.
There are no further button options upon “Extra
Long” button press.
4) To turn on the device again, follow Step 1) above.

Note:
(i) if the manometer does not start when ou press and hold the
button for more than 3 seconds, ou can tr to:
open the batter door and check if there are batteries
inside;
if there are batteries, close the batter door again. At this
time, it should automaticall start displa without an
button press.
If none of the previous tr works, tr to use 2 new AA
batteries. Follow the “Changing Batter ” section.
(ii)The “Zeroing” function stores the new offset value into flash
memor so it remembers the last offset value the next time the
device boots up.

3. OLED Screen Overview
The OLED displa not onl shows pressure readings but
also other useful information. For example, the “AVG”
screen indicates that the average of 10 seconds is shown in
Figure 3.1. The screen displa includes:
Screen Name: There are “LIVE” screen for 1 second
average reading screen, and “AVG” screen for
average of 10 second reading;
Sensor Status: “A” means active readings and “V”
means void readings.
If the sensor status shows “V”, ou will need to
reboot the device to re-initial the sensor. You can do
that b either opening the batter door and then
closing it up as hardware reset, or shutting down the
device and waking it up again b pressing button.
Battery Percentage: if the batter is less than 0%, it
will automaticall shut down. Insert new batteries if
that happens.
Readings (Average or Live): the readings in the
middle row is the main reading at the current screen.
In the example below, it is the average reading of 10
seconds. If it is “LIVE”, it is the average of 1 second.
The reading at smaller font in the bottom row is the
live reading in this example. Note that there is no such
smaller reading in the “LIVE” screen.

Unit: the readings are in the unit of Pascal b default.
Users can change the unit to inches of water, through
the app.

4. Changing Batteries
The manometer uses two AA batteries. Follow these steps
to replace the batteries:
1) Unscrew the batter door screw;
2) Open the batter door;
3) Replace two AA batteries;
4) Close the batter door. Make sure the hinge catches;
5) Drive the batter door screw back in while holding
the door closed with our thumb.
