MiniMate Plus Operator Manual
The monitor powers up the sensors and displays the average and maximum difference read from
the sensors. This allows you to test the sensor by stimulating it (i.e., shaking a transducer or
blowing into a microphone) and observing the response.
4.3. Setups Key
The Setups key accesses the following items. The BlastWare III software is the easiest method to
setup the monitor. The following setups can be changed in the field using the monitor alone.
4.3.1. Sample Rate
The MiniMate Plus offers a number of sample rates in the advanced mode including 512, 1024,
2048, 4096, 8192, 16384 samples per second (32768 and 65536 optional). Histogram record
mode supports the 1024, 2048 and 4096 sample rates only (the 4096 sample rate can only be used
with a maximum of four enabled channels). The following table summarizes the sample rates and
the channels that may be used. Note that some sample rates operate on specific channels only.
