Sample Related Functions
The following sub-sections cover sample related functions.
4.3.1. Starting/Stopping
To start or stop a sample, press the START/STOP key. A sample event can be
manually started or stopped from either the Operate Screen or the menu.
4.3.2. Real-Time Serial Output
GT-526S provides real-time output on the serial port at the end of each sample. The
format of the output is controlled by the printer mode setting (section 5.2.4). Section 0
covers the real-time output format.
4.3.3. Samples
The Samples setting controls the number of samples to take. Repeat configures the unit
for continuous sampling. Single configures the unit for a single sample. 2-999
configures the unit for a number of samples. Samples are discussed in section 5.2.
4.3.4. Sample Time
The sample time determines the amount of time that counts are accumulated. The
length of the sample is user settable from 1
– 999 seconds and is discussed in section
4.3.5. Hold Time
The hold time is used when Samples is set for more than one sample. The hold time
represents the time from the completion of the last sample to the start of the next
sample. The hold time is user settable from 0
– 999 seconds and is discussed in
section 5.2.
4.3.6. Count Mode
The count mode is used to set whether counts are displayed as Cumulative (normal) or
Differential. When in differential mode, the volume units will be preceded with the delta
character
Δ.
Count mode is discussed in section 5.3.
