Model 1835-C - Newport Corporation

2.4.3 Meter Configuration
The Model 1835-C provides a method to save the configuration of the meter
and to recall that configuration for later use even if the meter has been turned
off. This is accomplished through configuration buffers maintained in nonvolatile
memory. Configuration buffers are numbered 0 to 9 with buffer 0
being a DEFAULT buffer which can only be recalled but not saved to. The
reset state of all the buffers except the default buffer is empty. Empty buffers
cannot be recalled.
A recalled configuration becomes the current configuration of the meter. Any
changes to the current configuration must be saved via SAVE CONFIG or they
will be lost when a new configuration is recalled.
The meter will not recall a configuration that is not compatible with the
detector calibration module currently plugged into the meter. Configurations
using the same model of detector are compatible while configurations using
different models of detectors are incompatible.
The default configuration of the meter depends upon the detector family. The
list of configuration parameters stored in a configuration buffer as well as
their default values versus detector family are listed in Table 9 below:
