First, the operation
1, press the power button, power on, display digital flashing stable in the range of 00.0 ± 0.3 (gear selector in any one of the stalls). About 40 seconds after turning power is automatically turned off so the battery is in working condition for a long time. The boot can be shut down, press the OFF button at any time the battery for longer periods of time.
Tip: the TDS100 apparatus when the battery voltage (to show LOBAT) can still work properly does not affect the measurement accuracy and extend the battery life of more than 30%. Until the display without a digital display when replacement battery.
2, when turned on, the LCD screen is not displayed in the range of 00.0 ± 0.3, you can not tune 0:00. TDS100 instrument is a relative value, such as the boot of the instrument does not display zero, then the measurement value less the boot display the correct moisture content is measured object. That is, boot boot up the number of a negative sign, measuring the number of absolute value is measured object to the correct moisture content; such as the boot display to show the absolute value of the number of power reduction the number of positive measure. is the correct moisture content of the analyte.
Tip: When turned on, the LCD display can also be adjusted to zero within the range of 00.0 ± 0.3. Keep the battery cover is opened to remove the battery inside the battery compartment ten regulator clockwise adjust the displayed value is larger, counterclockwise tune the displayed value is smaller.
TDS100 induction moisture measuring humidity instrument electromagnetic wave penetration depth is 60mm, so by measuring the thickness less than 60mm, to overlay measurement, overlay thickness shall be not less than 60mm.
Second, the measurement
TDS100 instrument using the ASIC to ensure the moisture measurement of high sensitivity and accuracy. Even small changes in moisture content, the instrument can be reflected. Therefore, it is highly accurate moisture measurement instrumentation. To adapt to the measurement of different density substances, five stalls were set at the top of the measuring humidity instrument selector switch to adjust according to the following stalls.
Stall air dry density
1 0.40--0.55g/cm ³
2 0.55--0.65g/cm ³
3 0.65-0.75g/cm ³
4 0.8--0.95g/cm ³
5 1.00-1.25g/cm ³
Use when you're the bottom of the instrument flat on the material to be detected and measured surface must be flat, it will lead to measurement error. If the moisture content of the material to be detected is uneven, measurements can be measured at several points, and then calculate the average, the average moisture content.
Tip:
1, the instrument sensor in the box at the bottom of the instrument (Built), dimensions: length 45mm, width 44mm. Therefore, the surface of the material to be detected is greater than the surface of the sensor.
2, around the detected objects can not have other objects such as iron, magnetic induction material. Otherwise, the measurement results are inaccurate.
3, the apparatus of electromagnetic wave penetration depth of 30mm, it detected the thickness less than 30mm, to overlay measurement. Otherwise, it will affect the measurement results.
Third, the technical parameters:
A measuring range: 0 to 120%
2, Resolution: 0.1%
3: Big 3 ½ LCD LCD
4, electromagnetic scanning depth: 60mm
5 stalls: 5 files
6, Power: 9V (6F22) battery is a
7, the working environment: -5 ℃ to 50 ℃, relative humidity <80%
8, size: 120mm × 62 mm × 27 mm
9, Weight: 180g
Fourth, stalls accurate choices:
The first few pieces as possible to maintain the equilibrium moisture content of the specimen were measured on the gear position selector switch 5, respectively, write down the measurements of each stall. Based on dry weight balance method to the determination of the moisture content of the specimen. Select the switch which corresponds to the dry balance weight determination of the position of minimum deviation, after selection can be used as the testing of such substances.
Five, the warranty instructions
1 year warranty from date of purchase.
2, man-made damage or unauthorized users disassemble no warranty. |
