During vacuum process, a vacuum leak process will
be provided to check system for potential leaks.
Default value is 10 minutes. Press START key.
The calibration of the weight scale in the RHS980 can
be easily checked using this procedure. A steel ball of
a precise weight is provided with the RHS980 for
performing this calibration check. Unit must show
positive weight on scale prior to selecting this
procedure. Press YES key. Access to unit calibration
must be verified by service manager by entering a
password.
The screen prompts to attach the steel ball to the
bottom of the machine. There is a small post which
protrudes through the bottom plate of the RHS980
(see Parts Identification at rear of this Operation
Manual). This post is magnetic. Attach the calibration
check weight (steel ball) to this post. Press START
key.
This screen will display if the weight scale is in
calibration. If calibration check failed, the RHS980
must be fully calibrated. See below.
This screen will display if the weight scale is not in
calibration. To perform a full load cell calibration
procedure, press START key.
Press YES key if a calibration is required. Otherwise,
press NO key. Special RTI 4 KG (8.8 LB) weight IS
required to calibrate the scale, do not use steel
ball supplied with the machine! Unit must show
positive weight on scale prior to selecting this
procedure. Load cell calibration should be performed
by qualified technicians only and should be performed
at least once per year. Call RTI technical support for
more information. 1-800-468-2321 X 1
The screen prompts to attach the 4 KG (8.8 LB) weight
to the bottom of the machine. There is a small post
which protrudes through the bottom plate of the
RHS980 (see Parts Identification at end of this
Operation Manual). This post is magnetic. Attach the 4
KG calibration weight to this post. Press START key.
The weight scale is now calibrated. Remove the
calibration weight. Press START key.
This screen will display if the weight applied does not
meet the minimum required. For example; attempting
to use the calibration ball instead of the approved 4
KG (8.8 LB) calibration weight. Perform a shop load
cell calibration procedure or call RTI technical support
for more information. 1-800-468-2321 X 1
RTI recommends checking calibration every 3 months
