LBT-1710 Alkali-Resistant Glass Fiber Mesh Rapid Test Heating Device Test Chamber (New Standard)

Description

Product Introduction:

The LBT-1710 glass fiber mesh alkali resistance test rapid‑method heating device test chamber complies with GB/T 20102‑2026, “Test Method for Alkali Resistance of Glass Fiber Mesh—Sodium Hydroxide Solution Immersion Method,” and enables rapid determination of the alkali resistance of glass fiber mesh. This testing instrument features a modular design and employs a fully integrated instrumentation control system to achieve an optimal cost‑performance ratio. It delivers fast, accurate measurements, exhibits stable and reliable performance, and is easy to operate.

Instrument Parameter Settings

1. Definition of the control panel:

“ ”: [Setting Key]: Enters, switches between, and exits the parameter-setting mode, or displays the current status;

“ ”: [Left Shift Key]: Moves the selection left to the data bit you wish to operate on; the selected digit flashes as an indicator.

“ ”: [Decrease Key]: Used to decrease the value in parameter-setting mode.

“ ”: [Increase Key]: Used to increment the value when in parameter-setting mode;

2. LED display in measurement mode:

The upper row displays the real-time measured value, while the lower row shows the setpoint. Temperature readings are formatted as three digits, ranging from 00.0 to 99.9°C.

3. Control Value Setting:

In measurement mode, press “ “A few seconds later, the system enters the control parameter setting mode. At this point, the data field of the value to be modified will flash; press…” ” “ “Modify the flashing bit value, then press “ “Use the left arrow to select the data bit to be set; the selected bit will flash as an indicator. If a particular parameter has been modified or does not require further adjustment, you can press…” Press the “ key to directly proceed to modifying the next parameter. Once all parameters have been set, press “ When the “key” is pressed, the instrument automatically saves the setpoint and exits the setting mode, returning to normal measurement mode.

Display and Troubleshooting of Instrument Malfunctions:

1. When “hhhh” is displayed, it indicates a temperature overflow or an open circuit in the sensor. Verify that the sensor model matches the instrument and check whether the sensor is open-circuited.

2. When “LLLL” is displayed, it indicates that the temperature is too low or the sensor is open-circuited; check whether the sensor is connected in reverse.

3. If the temperature deviation is excessive, verify that the sensor model complies with the instrument’s specifications and confirm that the sensor is connected correctly.

4. If you suspect that the sensor and instrument are not functioning accurately, place the sensor separately in boiling water or an ice‑water mixture; the instrument should display approximately 100°C or 0°C, respectively. When the error is significant, it is usually due to a mismatch between the sensor’s calibration code and the instrument.

5. If the instrument’s display digits are noticeably flickering or the temperature reading deviates significantly, please check whether the supply voltage is too low and ensure that it complies with the specified technical requirements.
