Advice
Respected user:
If you are using this product for the first time, please note the following:
At the beginning of the measurement, first open the flow valve on the panel, then
use the needle valve on the instrument to measure the flow.
This device has a built-in large-capacity lithium battery that can work continuously
for more than 10 hours when fully charged.
When the integrated tester is left unused for a long time, some air will remain in
the test pipe and air chamber.In the first test, the high humidity gas will affect its test
speed (for micro water detection). Before measuring the SF6 gas to saturation, it is
necessary to take away the moisture in the air. So we will find that when testing the
second SF6 electrical equipment, it will be much faster (3-5 minutes).
Thanks for your cooperation!
