Product Parameters:
Product Name: Color Screen Multifunctional Signal Generator
3 power supply methods: external terminal DC 24V/USB-C/(with battery) built-in lithium battery
Battery type: Built in 3.7V 1500mAh lithium battery
Interface: Type C interface
Display screen: 2-inch TFT color display screen (320 * 240 pixels)
Display interface: switchable between Chinese and English interface
Knob: EC11 digital encoder knob (20 grids per turn, with buttons)
Terminal plug specification: 15EDGK3.81 (9P)
Working environment: 0-40 ℃, relative humidity<80%
Application scenarios: industrial control DC analog signal debugging, electrical equipment installation and maintenance, PWM motor speed regulation, etc
Voltage output range: ± 12V (maximum 20mA with load, with short circuit protection)
Voltage measurement range: ± 50V
Current output range: 0-24mA (maximum sampling resistance of 500 Ω, can be short circuited)
Current measurement range: ± 50mA
Output adjustment range: can be set arbitrarily, such as 0-20mA/4-20mA/0-10V/0-5V, and the corresponding engineering display value can be set by the user
PWM pulse square wave output: frequency adjustable 1-150kHz, duty cycle adjustable 0-100% (high level fixed 5V, driving current<20mA, with short circuit protection)
(Note that this PWM output is not suitable for 12V or 24V systems, as 5V is considered a low level for them):
Power supply instructions: 3 power supply methods, can be charged/operated with a mobile phone charger, power bank, or external 24V:
1. External wiring terminal power supply DC 24V ± 4V, power 2W (non charging)/5W (charging)
2. External USB-C 5V, current 0.4A (non charging)/1A (charging)
3. (with battery) Built in 3.7V lithium battery, maximum charging current 0.8A, fully charged battery indicator light turns green and automatically does not charge, usually takes more than 6 hours, fully charged can take 1-5 hours depending on the output load size
Charging status description:
1. In the shutdown state, when the charging port is connected to Type C charging, the charging indicator light below is red, and when fully charged, it is green
2. In the power on state, when the charging port is connected to Type C charging, the charging indicator light below is red, and the battery level in the upper right corner of the screen is green, repeatedly increasing the battery level (regardless of how much power is left before charging, it will be green when starting charging). When fully charged, the charging indicator light below is green, and the battery in the upper right corner of the screen is green and does not flash. When disconnecting the Type C charging plug, the battery in the upper right corner of the screen displays white
Notes:
1. Turn off the power first and then connect the wires;
2. Exceeding the range indicated by the technical specifications may cause the instrument to malfunction or even be damaged
Frequently Asked Questions:
Q: How to set the duty cycle of PWM, switch and adjust the frequency Hz/duty cycle%
Answer: Press the key to enter PWM regulation, press the knob once to switch the PWM regulation state (frequency 1-150000Hz/duty cycle 0-100%). The corresponding character units are displayed below the PWM
