Load current of switch
output exceeds 80 mA.
Shut off the power
supply. After elimi-
nating the output
factor that caused
the excess current,
turn the power
supply back on.
Residual
pressure
error
A pressure level grea-
ter than
±
7%F.S. has
been applied when it
is cleared to zero. The
switch will automati-
cally return to measu-
ring mode in three se-
conds, however. Due
to individual product
differences, the set-
ting range varies by
±
1 digit.
Bring the pressure
back to atmospheric
pressure and try
using the zero-out
function.
Applied
pressure
error
Supply pressure ex-
ceeds the maximum
set pressure.
Bring the pressure
back to within the
set pressure range.
Supply pressure is be-
low the minimum set
pressure.

This function eliminates slight differences in the output values and
allows uniformity in the numbers displayed. Displayed values of the
pressure sensor can be calibrated to within
±
5% of their readings.
Peak/Bottom hold funct

This function constantly detects and updates the maximum and mini-
mum pressure values and allows the unit to hold the display value.

A large bore cylinder or ejector consumes a large amount of air in
operation and may experience a temporary drop in the primary pres-
sure. This function prevents detection of such temporary drops in pri-
mary pressure as abnormal pressure.
