The zero can be adjusted by pressing the up and
down arrow keys (). The adjustment range is
equal to ±1% of the full scale value that has been
selected. For example: for a full scale value of 1.000,
the zero can be adjusted ±0.010; for a full scale
value of 1000.0, the zero can be adjusted ±10.0.
NOTE: Make sure that no signal is connected when
setting the zero.
The span can be adjusted from 0.100 to 1.900 by
pressing the up and down arrow keys (). This
factor is a value that all readings will be multiplied
by. (The signal reading is shown until the arrow keys
are pressed, then the span factor is shown. Once the
span factor is chosen, the next reading displayed is
the signal reading times the span factor.)
The low alarm choices are values between zero and
full scale. To turn the alarm off (disable), select a
value less than zero or greater than full scale. Use
the up and down arrow keys () to adjust the
value.
The high alarm choices are values between zero and
full scale. To turn the alarm off (disable), select zero
or a value greater than full scale. Use the up and
down arrow keys () to adjust the value.
Using the up and down arrow keys (), choose
between latch and unlatch. When the LEDs are
latched, they will remain lit if an alarm condition had
existed and then returned to normal operating
conditions. When the LEDs are unlatched, they will
only remain lit while an alarm condition exists.
Using the up and down arrow keys (), choose
either latch or unlatch. When latched, the relays will
remain closed if an alarm condition had existed and
then returned to normal operating conditions. When
unlatched, the relays will only remain closed while an
alarm condition exists.
Using the up and down arrow keys (), choose
either ON or OFF. When the audible alarm is ON,
choose between latch or unlatch. When latched, the
audible alarm will remain on if an alarm condition
had existed and then returned to normal operating
conditions. When unlatched, the audible alarm will
only remain on while an alarm condition exists.
