9 VERIFICATION
The purpose of this procedure is to verify span accuracy upon installation of the Servomex
SpectraScan Gas Analyzer. This procedure is also performed at periodic intervals throughout the
effective life of the unit. This procedure has three parts: Setup, Zeroing and Span Verification.
Zeroing is a measurement on a zero (inert) gas. Span verification is a measurement on the
customer’s trusted, certified mixture(s).
9.0 Procedure
9.0.1 Setup
1. Communicate with the analyzer via Modbus/TCP: Refer to the Modbus register map
in the Applications Manual to be used to configure customer’s Modbus Master
Program (not provided by Servomex.)
2. Ensure that the Servomex SpectraScan Gas Analyzer is sufficiently warmed-up.
Warm-up: The unit’s interior is temperature-controlled and will only meet measurement accuracy
specifications when sufficient time is allowed for the unit to meet and stabilize to the designed
operating temperature. The red “Warm-Up” light on the display will remain on until the unit is
warmed-up. Warm-up time for the unit is approximately 30 minutes to 2 hours depending on the
ambient temperature. Do not begin to take data until the “Warm-up” light goes off and the “Run”
light (green) comes on. LED codes are as follows:
