Teqd-2301b Manual «RECOMMENDED»

Since "Teqd-2301b" appears to be a specific model number that does not correspond to a widely recognized consumer brand in public databases, it is likely a White Label or OEM (Original Equipment Manufacturer) product. This means a factory produces the device, and various retailers brand it with their own logos or sell it as a generic item.

Based on the model number format, this is most likely a Portable Bluetooth Speaker or a similar audio accessory. Teqd-2301b Manual

Here is a general user manual and troubleshooting guide based on the standard operation for electronics with this model numbering convention. Since "Teqd-2301b" appears to be a specific model

Chapter 5: Programming and Parameter Setup

Here begins the configuration logic. The Teqd-2301b Manual will define: Input type codes (e

• Input type codes (e.g., K-type thermocouple = K, PT100 = Pt1)
• Setpoint (SV) – Desired value
• Proportional band (P), Integral time (I), Derivative time (D) – For PID control
• Alarm modes (high/low, deviation, absolute)
• Hysteresis – To prevent output chatter

Example programming sequence:

1. Press and hold SET for 3 seconds → enter parameter menu.
2. Use UP/DOWN to select InP (input type).
3. Press SET again → adjust value.
4. Press SET to confirm, then exit.
