10.4 Front Panel Calibration by Functions
10.4.1 Introduction
Sub-section 10.4 is a guide to the process of calibrating the Model 9100's functions from
the front panel. The following topics are covered:
10.4.2 Summary of Calibration Process
10.4.2.1
General Procedure
10.4.2.2 Sequencing Calibrations
10.4.3 DC Voltage Calibration
10.4.4 AC Voltage Calibration
10.4.5 DC Current Calibration
10.4.6 AC Current Calibration
10.4.7 Resistance Calibration
10.4.8 Capacitance Calibration
Function Calibration Performed
Capacitance optionally via Resistance
Conductance via Resistance
Frequency at manufacture
Mark/Period at manufacture
% Duty at manufacture
Temperature - Thermocouple via DC Voltage
Temperature - RTD via Resistance
Logic Pulses at manufacture
Logic Levels via DC Voltage
For functions other than capacitance (which can either be calibrated directly or calibrated
via Resistance) there are therefore no calibration procedures, although confidence checks
for them can be performed (e.g. the Full Selftest procedure detailed in Section 8, sub-
section 8.3).
CJC Pod Calibration
Calibration of the CJC Pod (the external module which contains the Reference Junction
on its iso-thermal block for use with the Thermocouple function) is purely ratiometric,
and not dependent on the STD CAL of any function. The calibration should be performed
annually, close to the time of STD CAL. The CJC Pod calibration procedure can be found
in this section 10; sub-section 10.2.5.
Other Functions
No calibration is required for the following functions, as they are either calibrated for life
at manufacture, or calibrated automatically as a result of calibrating the functions listed
above, as shown in the table:
