Circuit power supply: 24V ± 10% maximum current 30mA Temperature effect: (0.0003% reading+0.0001% f.s)/℃, from -10 ℃ to 15 ℃ and from 28 ℃ to 50 ℃. Measurement range input impedance: voltage range of 2M Ω; current range of 20 Ω. Output range load characteristics: Output current: Rl ≤ 500 Ω @ 20Ma; RL ≤ 1K Ω @ 10mA. Output voltage: IL ≤ 5mA. Mathematical calculation of measurement values and lookup tables for thermocouples and thermistors(This item is used to verify the instructions of the instrument, user disabled)When calibration is not allowed, i.e. do not enter the calibration state, select the measurement range. Press the "8/CALIB" key to perform mathematical operations on the current displayed value. The current displayed value is X, and the calculated displayed value is Y. The calculation expression is Y=Ax+b. When the values of a and b are valid, the "x" icon appears on the screen, and the displayed value is the calculated value. If measuring the "4~20mA" signal and wanting to calculate it as "0~100.00Kpa", input a=6.25; b=25。 When measuring thermocouples and thermistors, input a=0; B=I want to check the electromotive force value or resistance value in the table, and the result shows the temperature value corresponding to the input electromotive force value or resistance value. The cold junction compensation setting is also effective when measuring the thermocouple state. When the cold end compensation is set to 0, it corresponds to the ITS-90 indexing table. Cancel the mathematical operation function, press the "8/CALIB" key, do not enter data, press the "ENTER" key to skip, the "X" icon disappears, and return to normal state. When the measurement is in the power on state, press the "Measurement" button, and the screen will display the measurement range selection menu as shown in the figure below. Use the "∧" and "V" keys to select the measurement range. When the cursor stays on the range, press the "ENTER" key to confirm, and the instrument will enter the next selection measurement state. Use the "∧" and "V" keys to select the measurement range. After selecting the measurement range to be measured, press the "ENTER" key. Press' CLEAR 'to exit the measurement range selection and return to standby mode. III Product functional features: 1. Measure and output voltage, current, resistance, thermocouple, and thermistor signals simultaneously, and isolate the measurement and output from each other. 2. The button controls the output function of any step, making it more convenient to check linearity and saving time compared to traditional knob style. 3. Provide a 24V power supply for the transmitter to directly measure current in the circuit, making it more convenient to detect two-wire transmitters. It also has the function of simulating transmitter output. 4. Eight types of thermocouples and three types of thermal resistors have ITS-90 standard calibration table corresponding displays. External or built-in temperature sensors provide cold end temperature compensation for thermocouples, or manual cold end temperature compensation function can be selected. 5. Ensure high accuracy within a wide temperature range and display up to five digits. Large screen LCD with backlight, Chinese intelligent menu, more comprehensive parameter display, and easier to use. 6. Using panel calibration technology, there is no need to open the instrument case, making it easier to trace the instrument to the previous level standard. 7. Power saving management, longer usage time, automatic shutdown under low power. |
