The HT1109 meter uses high-speed Σ-Δ analog-to-digital conversion technology. It is suitable for control occasions such as electronic batching scale, fixed value scale, sorting scale, etc. It also has upper and lower limit alarm and peak hold function.

new features: 
1. Analog isolation output;
2. The software operation menu is simplified, and one button enters the set target state;
3. Independent menu mode, common parameters and advanced parameters are set independently.

basic skills:
3-channel optical isolation switch input, 3-way switch (built-in 3-way relay) output control
High-precision A/D conversion with readability of 1/30000
5-point nonlinear correction
The table change does not need to be recalibrated, just enter the parameters of the original meter to use
Set plus / subtraction scale / sorting scale / upper and lower limit alarm / peak hold and other functions in one
Quantitative value, advance amount, upper and lower limit, node delay and other parameters can be freely set according to the application.
1-2 kinds of ingredients can be selected in the add/subtract scale mode, and the external control/self-test/free upper and lower limit modes can be selected in the sorting scale mode.
