5. Operation and MENU description
5.1 Check the product specifications
Before starting to use this product, check the product specifications that can be found in this manual
or the basic information located on the back panel of the product.
The detailed product information
can be found in Section
6. Be particularly cautious about the
supplied voltage indicated in the specification. A higher voltage may lead to irrecoverable damage,
and a lower voltage will not power the product for any desired functions.
For the best performance of the product, it is advised that the gas to be measured must be clean and
free of particles or other foreign materials.
5.2 Check the leakage
Check gas leakage before any measurement. If it is needed, pressurized nitrogen or air can be used
for the leakage check.
5.3 Power the meter and digital data connection
Although this product complies with the CE-
required EMC regulations, it also requires the product to
be used according to the standard electrical device practice. For normal oxygen therapy, the meter
can be powered by 4-AA batteries. Be sure to select the batteries with safety proof and within the
expiration date. Do not use batteries without a known manufacturer and expiration date. For
extensive usage, it is recommended to have the meter powered with external DC power or an AC-DC
adapter. Make sure the output voltage is within the range of the specified ones in Section 7. Before
connecting the product with the external power, make sure the standard electrical device
precautions such as EDS (electrostatic discharge) and DC voltage are observed. Excessive
electrostatic discharge may damage the p
roduct.
The power and data ports are standard Type-C USB port. The manufacturer-supplied Type-C USB
cable has the screw locking fixture. It is recommended such a feature to ensure the cable is properly
engaged and will not be accidentally got unplugged.
Half-duplex RS485 Modbus is used for digital data communication. Make sure the wires are properly
connected to the receiver side.
