Menu Functions:
Peak: This indicates the peak capture function. The default setting is Peak
set and the peak reading is displayed. By pressing F1 the previous
peak reading is reset and a new Peak reading is captured and
displayed.
Unit: Pressing F2 will set the unit selected. There are 10 engineering
units available for selection. These are ‘atm’, ‘kg/cm2’, ‘inHg’,
‘inH2O’, ‘psi’, ‘mbar’, ‘mmH2O’, ‘mmHg’, ‘cmH2O’ and ‘kPa’.
The unit selected will be saved to the memory before power down
as default value on next power up. This function is useful when
dealing with only one engineering unit.
Zero: Pressing F3 will set the reference pressure to zero. Prior to setting
the zero reference pressure, all pressure sources should be
disconnected from the unit. This is useful if the zero pressure
reading changes due to atmospheric pressure variations and
sudden changes of operating temperature.
Setup: Pressing F4 will toggle the display to the setup menu. There are
four selections similar to the main menu. For details follow the
setup menu descriptions below.
Setup Menu
The setup menu has many options such as Saving and exporting data, setting the clock,
back light and Relay control Setting (Machine Setting).
The following is the screen shot of the Setup Menu. Four menu selections are available
in this menu. These are “Records”, “Clock Settings”, “Back Light”, “Machine Setting”.
The default selection is highlighted with blue background.
Menu selections are interactive. Each of these can be selected from top to bottom by
pressing F3 (“Next”) or using right arrow (>) or bottom to top by pressing F2 (“Prev”) or
left arrow (<). To select the highlighted function press F1 (“Sel”). To exit the menu press
F4 “(Exit”) or press key “ESC”. Screen shots of each of these menu selections are

Initial Setup
Prior to using the unit, make sure the internal LI-Ion Polymer battery is fully charged. It
takes about 3-4 hours using the charger supplied with the unit. When the battery is fully
charged the red LED on the charger will turn to green.
DigiMano 2500 Pressure /Vacuum differential models are equipped with two ports at the
bottom of the unit. The Left Port marked ‘Port 1‘ is for measuring positive Pressure and
the right port marked ‘Port -2 ‘is for measuring Vacuum.
Whereas DigiMano 2500 Gauge Pressure /Vacuum models have only one pressure port
that is compatible with non corrosive gases and fluids.
Precautions
Caution:
DigiMano 2500 Pressure Vacuum Dual Port Models:
Only Port 1 (pressure) is fluid compatible. Introducing fluid into Port 2
(vacuum) will damage the transducer and thereby void the warranty. Do
not attempt to measure differential pressure as one port need to be open
to atmosphere for making measurements.
All DigiMano 2500 Gauge Pressure Models:
Do not exceed the maximum pressure. When the pressure reaches
the maximum limit the display flashes “Over Pressure” and will hear
a beep till the pressure reaches below the range.
Do not use any corrosive fluids that might damage the transducer.
The unit is supplied with a Li battery charger. Do not use any other
Power supply or charger as it will damage the battery.

Getting Started
Pressure Connection
DigiMano 2500 (Pressure /Vacuum Dual Port Model) is provided with two ports, Port 1
and Port 2 fitted with quick connect fittings. Port 1 is for positive pressure measurements
and Port 2 is for Vacuum measurements. When making Pressure measurements Port 2
must be left open to atmosphere and vice versa when making vacuum measurement.
DigiMano 2500 Gauge pressure /Vacuum single port models have only one port with
1/8”-27 NPT pressure connection.
Measurements
Turn unit power on by pressing the “ON” key. On power up, the display shows the
model and software revision for about 5 seconds and switch to the main menu similar to
the one shown below.
Main Menu Display
Select the desired engineering unit by pressing F2. The selected engineering unit is
saved in the nonvolatile internal memory as default selection on the next power up. The
following engineering units are available.

Pressure Measurement – DigiMano 2500 Dual port Models
Connect the pressure line (if going to read positive pressure) to Port 1 (using the male
quick connect supplied with the unit) till it locks in place. Leave the Port 2 open. With no
pressure applied the reading should be zero. If not zero the unit by pressing F3 key.
Apply the pressure and the pressure reading will be displayed along with the peak
pressure. The peak reading can be reset by pressing F1 (Peak). This will be useful if the
pressure is changing rapidly or detecting leak in the system.
Vacuum Measurement– DigiMano 2500 Dual port Models
Connect the vacuum line to Port 2 (using the male quick connect) till it locks in place.
Leave the Port 1 open. Apply vacuum and the vacuum reading will be displayed.
If vacuum is applied to the pressure port (P1) a warning beep and a message “Switch
Port” will be displayed.
Caution: Port 2 is air only. Inadvertently Introducing fluid Port 2 (vacuum) will damage
the transducer and thereby void the warranty.
Pressure /Vacuum Measurement – DigiMano 2500 Single port Models
Connect the pressure line to the 1/8”-27NPT pressure port using the necessary
adapters supplied. With no pressure applied the reading should be zero. If not
press F3 and zero the pressure. Apply the pressure and the pressure reading will
be displayed along with the peak pressure. The peak reading can be reset by
pressing F1 (Peak). This will be useful if the pressure is changing rapidly or
detecting leak in the system.

Real time data can be uploaded to the PC using HyperTerminal or any serial data
Capture utility software. The data flow control is as follows:-
Baud Rate: 9600
Data Bits: 8 Bits
Parity: None
Stop Bit: One
Flow Control: Hardware.
Note: For PCs without serial port use any serial port to USB adapter cable.
Follow the operating system for the PC to setup the HyperTerminal or other data
capture software.
Once the HyperTerminal is setup (or any data capture software is setup and ready to
use) connect the DigiMano 2500 to the PC using the 9 Pin RS 232 cable or the RS 232
to USB interface cable. Turn the unit ON. If the communication settings are correct, as
specified above, a header will appear in the capture window on the PC with the following
information as below. The data capture rate, the interval and the unit selected will
appear blow the header. The data will be output at the interval selected in the “set

Measurement data is also saved into the internal EEPROM memory (1M) at the elected
data capture rate (0.5 seconds to 15 minutes). Even though more than 10,000 records
can be saved in the memory, it will get full if the data capture rate is set at a fast rate.
When the internal memory is full the data gets overwritten. Therefore it is advisable to
export the data periodically to the PC for future analysis.
Export Data
