ENERAL ROUBLESHOOTING
The calibrator has been designed so that problems can be rapidly detected, evaluated and
repaired. During operation, it continuously performs diagnostic tests and provides the
ability to evaluate its key operating parameters without disturbing monitoring operations.
A systematic approach to troubleshooting will generally consist of the following five steps:
1. Note any warning messages in the Alerts page and take corrective action as
2. Examine the values of functions and compare them to factory values. Note
3. Use the internal electronic status LEDs to determine whether the electronic
4. Suspect a leak first!
5. Refer to the Dashboard to confirm that the calibrator's vital functions are

CAUTION – TECHNICIAN REQUIRED
The operations outlined in this chapter are to be performed by qualified
maintenance personnel only.
WARNING – ELECTRICAL SHOCK HAZARD
• Risk of electrical shock. Some operations need to be carried
out with the instrument open and running.
• Exercise caution to avoid electrical shocks and electrostatic or
mechanical damage to the calibrator.
• Do not drop tools into the calibrator or leave those after your
procedures.
• Do not short out or touch electric connections with metallic
tools while operating inside the calibrator.
• Use common sense when operating inside a running calibrator.

voltage test points on the power distribution board. (The calibrator's DC
power wiring is color-coded and these colors match the color of the
corresponding test points on the power distribution board).
• Technical Support data indicate that the majority of all problems are
eventually traced to leaks in the internal pneumatics of the calibrator or
the diluent gas and source gases delivery systems.
• Check for gas flow problems such as clogged or blocked internal/external
gas lines, damaged seals, punctured gas lines, a damaged /
malfunctioning pumps, etc.
