Manual Calibration Checks With Izs Or Zero/Span Valves; Figure 7-3: Setup For Manual Calibration Check With Z/S Valve Or Izs Option - Teledyne 100E Instruction Manual

Calibration Procedures
7.6. Manual Calibration Checks with IZS or Zero/Span
Valves
Zero and span checks using the zero/span valve or IZS option are similar to that
described in Section 7.3, except:
• On units with an IZS option installed, zero air and span gas are supplied to the
analyzer through the zero gas inlet and from ambient air.
• On units with a zero/span valve option installed, zero air and span gas are
supplied to the analyzer through the zero gas and span gas inlets from two
different sources.
• The zero and calibration operations are initiated directly and independently with
dedicated keys CALZ and CALS.
To perform a manual calibration check of an analyzer with a zero/span valve or IZS
Option installed, use the following method
STEP ONE: Connect the sources of Zero Air and Span Gas as shown below.
