Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 19704-2005 "Hydrological Instrument Display and Record", compared with GB/T 19704-2005, except for editorial repair
In addition, the main technical content changes are as follows.
--- The scope has been modified (see Chapter 1, Chapter 1 of the.2005 edition);
--- Modified the classification (see Chapter 4, Chapter 4 of the.2005 edition);
--- Added "GB/T 13983 Instrumentation Basic Terminology" "GB/T 17626.8 Electromagnetic Compatibility Test and Measurement Technology
Normative reference to "frequency magnetic field immunity test" and "General technical conditions for SL149 hydrological data solid state storage device";
References to the “small batch count sampling inspection procedures and sampling tables for GB/T 13264 nonconforming product rates”;
--- Modified the performance statement on the record (see 5.5, 5.7,.2005 version 5.1.4, 5.1.5, 5.1.6, 5.3);
--- Removed the "print record" aspect (see 5.3.2 of the.2005 edition);
--- Modified "Test conditions and methods" (see Chapter 6, Chapter 6 of the.2005 edition).

The terms and definitions defined in GB/T 13983, GB/T 19677 and GB/T 50095 apply to this document.
4 classification
4.1 Form
Display and record are divided into.
a) Stand-alone. display and recording functions are implemented by separate devices;
b) Functional. The display and recording functions are integrated in the hydrological instrument.
4.2 Display mode
Display and record are divided into display modes.
a) electronic. display digital, graphic, text, symbol and color standard in various electronic display devices;
b) Characterization, character display. The font is fixedly printed and scored on the measuring instrument and used as manual observation data.
4.3 Recording method
Display and record are divided into recording methods.
a) digital. store hydrological data in a semiconductor memory according to certain rules;
b) Non-digital. The process of changing the hydrological data over time is recorded on paper.
