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 technical specifications can be found in Section 7. For a specific application,
the pressure rating must not be higher than the system pressure to be measured, and the flow range
should also be within the specified ones. In most cases, the use of a high full-scale ranged meter for
the very low flow rate measurement often results in erroneous data. The gas to be measured must
also be consistent with that specified by the product. 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. Before connecting the meter with
external DC power or an AC-DC adapter, make sure the supply voltage is within the range of the
specified ones in Section 7. Be cautious that the standard electrical device precautions such as EDS
(electrostatic discharge) and DC voltage are observed. Excessive electrostatic discharge may
damage the product.
The manufacturer-supplied power and data cable have a locking fixture. Lock the cable and make
sure it is properly engaging 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.
