joy-it JT-UM120 USB Multimeter
PRODUCT DESCRIPTION
The JT-UM120 is the digital all-round multimeter. USB ports often differ greatly in their quality and available power. With the JT-UM120, you can conveniently keep track of all measured values and also have a quick-charge trigger for mobile communication devices. The versatile display modes, such as overview measurements, detailed measurements and real-time graph view, offer a particularly wide range of analysis options.
Additional functions such as evaluation via separate PC software, automatic, orientation-controlled display rotation, cable resistance measurements round off the overall package.

MAIN VIEW
MAIN VIEW: Only the 3 main parameters (voltage, current & power), as well as the current temperature, are displayed here.
Press the multifunction switch to pause or resume the measurement.
By turning the multifunction switch to the left or right, it is possible to switch between the individual views.
DETAIL VIEW: Further information and statistics are displayed here.
Press the multifunction switch to open the function menu. Here you can switch between the individual groups, as well as start and reset recordings.
WAVEFORM VIEW: Here the measurements are displayed in a waveform.
Press and hold the multifunction switch to the left to decrease the time base.
Press and hold the multifunction switch to the right to increase the time base.
Press the multifunction switch briefly to pause or resume the curve.
Press and hold the multifunction switch to switch between the individual modes.
APPLICATION VIEW: Here you can open the various applications such as Fast Charge, Statistics, the Toolbox and Settings.
FAST CHARGE
AUTOMATIC DETECTION : Here the device tries to trigger different protocols. After the test process is completed, an overview of the supported or unsupported protocols is automatically displayed.
As an alternative to automatic detection, it is also possible to select between different PD protocols, QC2.0, QC3.0, FCP, SCP, AFC, VOOC/WARP and SVOOC 1.0/SVOOC 2.0. Individual voltages can also be selected in the individual protocols with which the protocol is to be triggered.
Attention! Beware of high voltages at the output of the device! Avoid direct contact with the output to reduce the risk of electric shock or injury.
Please note that during automatic detection, the corresponding voltage is also present at the output of the device. Therefore, disconnect all connected devices to avoid a defect at your device.
STATISTICS
In the statistics menu you can choose between energy statistics, battery capacity calculation and offline recording.
ENERGY STATISTICS: The individual recording groups are listed here. These can each be either selected as the active group or reset.
BATTERY CAPACITY CALCULATION: To determine the battery capacity, first select a recording group, as well as the battery voltage (3.0 V to 5.0 V possible) and the efficiency (80% – 100% possible). The measurement starts automatically.
OFFLINE RECORDING: Press the multifunction switch here to start or delete an offline recording.
TOOLBOX
Additional functions are available in the toolbox:
CABLE RESISTANCE DETECTION: Measures the internal resistance of a cable – Must be performed under a constant current load.
PD DETECTION: Monitors the PD communication. The PD switch must be set to ON. Furthermore, 2 USB-C cables (Type-C IN & Type-C OUT) must be used.
PD CONVERTER: Enables PD communication with QC2.0 chargers. Set The PD switch must be set to ON here. First set the maximum packet power here. Make sure not to exceed the maximum power of your charger here.
USB-C CABLE: Requires a Type-C cable with an E-Marker chip. If your interface does not contain this chip, the packets cannot exceed a current of 3 A.
DASH CABLE: Reads out the data from the DASH chip.
SIMULATE DASH: Can be used to use VOOC/WARP over a normal cable. Instead of a USB-A to Type-C DASH cable, a Type-C to Type-C cable can now be used here.
ANALOG APPLE 2.4 A: Allows charging at 5 V and 2.4 A.
SETTINGS
GENERAL
BRIGHTNESS: Sets the display brightness.
STANDBY BRIGHTNESS: Sets the display brightness in standby mode.
STANDBY TIME: Defines the time to automatically switch to standby mode.
REFRESH RATE: Sets the refresh rate to Slow, Medium, or Fast.
