Manual Calibration Without Zero/Span Valves; Figure 7-1: Pneumatic Connections For Manual Calibration W/O Z/S Valves - Teledyne 300E Instruction Manual

Model 300E Carbon Monoxide Analyzer
Instruction Manual
Sections 7.2 and 7.3 describe procedures for performing manual Zero and Span Calibrations on
your analyzer.
To perform a CHECK of the instrument's Zero or Span Calibration follow the same steps,
however, DO NOT press the ENTR key at the end of each operation.
Pressing the ENTR key resets the stored values for OFFSET and SLOPE and alters the
instruments Calibration.
When performing a CHECK ZERO, press the EXIT key to end the procedure.
