7 BASIC OPERATIONS
7.4.3 Locking the key of the test pressure gauge
Locking the gauge key prevents the keys from being accidentally pressed while in Measure mode.
1) Key lock set
2) Key lock released
7.4.4 Zero reset of the test pressure gauge
Under atmospheric pressure, the reading of the gauge can be reset.
Keep pressing and keys simultaneously resets the test pressure display to 0. Releasing the keys
completes the zero reset and returns to Measure mode.
7.4.5 Test pressure gauge error display
Error message
Cause
Corrective action
The load is short-circuited causing an
over current to flow.
Turn the power OFF and check the load.
Pressure is applied during zero-point
adjustment.
Applied pressure at the pressure port should
be brought to atmospheric pressure and
zero-point adjustment should be done again.
External input is carried out outside the
rated pressure range.
Applied pressure range should be brought
within the rated pressure range.
Communication error
(Disconnection, faulty connection, etc.)
Check the wiring when using the copy
function.
Communication error
(incorrect model.)
Make sure that the system is configured of
the same models when using the copy
function.
The applied pressure exceeds the
upper limit of the display pressure
range)
Applied pressure range should be brought
within the rated pressure range.
The applied pressure exceeds the
lower limit (reverse pressure)of the
display pressure range)
