HT1109 control instrument

The HT1109 instrument uses high-speed Σ-△ analog-to-digital conversion technology. It is suitable for electronic batching scales, fixed value scales, sorting scales and other control occasions. It also has upper and lower limits and peak holding functions.

 
new features: 
1. Isolated analog output;
2. The software operation menu is simplified, and one key enters the setting target state;
3. Using menu mode, common parameters and parameters are independently set.

basic skills:
3 optical isolation switch input, 3 switch (built-in 3 relay) output control
High-precision A/D conversion, readability up to 1/30000
5-point nonlinear correction
No need to re-calibrate when changing the meter, just input the parameters of the original meter to use
Integrate functions such as addition/subtraction scale/sorting scale/upper and lower limit alarm/peak hold
Quantitative value, lead, upper and lower limits, node delay and other parameters can be set freely according to the application
1-2 kinds of ingredients can be selected in addition/subtraction scale mode, and external control/self-checking/free upper and lower limit modes can be selected in sorting scale mode
