4. Design and function
b. Instrument calibration
Selecting this option allows the CTH7000 to be calibrated; this option will overwrite and
replace the existing calibration data. The correct equipment, environment and accurately
calibrated resistors are required. For this reason, a pass code (9900) has to be entered
first.
Selecting this option will overwrite the instrument calibration data.
Do not attempt to do this unless you have the correct equipment,
environment and suitably trained personnel.
Specialised equipment is required to proceed further with this procedure.
c. Factory defaults
The instrument parameters can be set to the factory defaults. Selecting this option will
overwrite any exiting calibration data. For this reason, a pass code (9900) must be
entered (see below).
