Klein Tools ET910 Manuel D'utilisation

ENGLISH
INSTRUCTION MANUAL - USB DIGITAL METER & TESTER - TYPE A
GENERAL SPECIFICATIONS
The Klein Tools ET910 is a USB digital meter and tester combination for USB-A (Type
A) ports. It accurately and reliably measures and displays the USB port voltage, current,
capacity, energy and resistance simultaneously. It can also test the maximum current
delivery capability of the USB port with built-in fixed loads so user need not connect to
an external load. It will function with any USB-A port that has the ability to deliver power.
It requires no batteries, as it draws power from the power source.

FUNCTION BUTTONS (FIG. 1)
MODE BUTTON 4 (Screen Toggle/Data Storage/Memory reset)
The Mode button serves three purposes:
1. Switch between screens (FIG. 2):
From the default screen, pressing and releasing once will switch to the
Memory Screen.
2. Data/Memory Storage:
To record a reading during live monitoring event, press and hold the Mode
button for 3 seconds. Release the button after the memory location (i.e. M:1)
flashes momentarily on the screen. The next set of readings will be stored at
the next available location until all 10 memory locations are used. NOTE: After
all 10 locations are used, subsequent readings will overwrite the original 10
stored readings, beginning with M:1. NOTE: When in the Memory screen, if the
Mode button is not pressed within 3 seconds, the display will return to the Default
screen.
3. Memory Recall/Reset:
When in the Memory Screen, repeated pressing will cycle through all 10
memory locations, beginning with M:1. You must scroll through all 10
locations to exit. NOTE: If no data has been stored into memory, pressing the
Mode button will do nothing. The ET910 will only display memory locations
containing stored data.
To reset or erase all data in memory, press and hold the Mode button for 5
seconds from the Memory screen until the letters CLR flash in the upper right
corner (Fig. 2). All data in memory will be erased in all 10 memory locations.
1. Power source INPUT (USB-A) A. DC voltage
2. Load OUTPUT (USB-A) B. DC current

FUNCTION BUTTONS (FIG. 1)
TEST LOAD BUTTON 3 (Selects current load to output)
The first press of the Test Load button will enter Testing mode, defaulting
to a test load value of 0.5A. To select a different value, press the Test Load
button repeatedly until the desired value is selected. Available test load
values are 0.5A, 1.0A, 2.0A, and 3.0A.
The selected load value is indicated by the red LEDs beneath the display.
Testing will initiate at the indicated load after three seconds of releasing the
Test Load button, so it is important to select the desired load quickly.
NOTE: The output USB 2 is disabled when the test load is used.
WARNINGS
To ensure safe operation and service of the tester, follow these
instructions. Failure to observe these warnings can result in severe
injury or death.
• This tester will NOT display current below 50 mA, even if it is allowing
this to pass through. NOTE: The display will show zero current.
• DO NOT use with ports that operate outside of the rated voltage and
current.
• Before each use verify tester operation by measuring a known voltage
or current.
• NEVER use on a circuit with voltage or current that exceeds the
maximums specified for this device. When maximums are exceeded,
the display will read "OVERLOAD" and the output port will be disabled.
• DO NOT use during electrical storms or in wet weather.
• DO NOT use if tester appears to be damaged.
• Use caution when working with voltages above 25V AC RMS or 60V DC.
Such voltages pose a shock hazard. NOTE: Voltage above 24V DC
will damage product.
• Always adhere to local and national safety codes. Use personal
protective equipment to prevent shock and arc blast injury where
hazardous live conductors are exposed.
CAUTION
• DO NOT attempt to repair this tester. there are no serviceable parts.
• DO NOT modify this tester in any way.
• DO NOT expose to extremes in temperature or high humidity.
• This tester will NOT be able to monitor a source port if any of the
following conditions occur:
• The USB port or plug is not properly connected.
• The source device shuts down. Some portable storage batteries
have auto-shutdown or standby modes to save power if no load is
detected from downstream device.

MONITORING MODE
NOTE: The input plug must be connected to a powered USB device before the downstream device
is connected to the output port. "Downstream device" refers to any device that has the ability to
draw current over USB.
1. Connect the input connector to the USB power source to be monitored
• The display will turn on with Klein Tools logo screen and move quickly to the Default Screen (FIG 2).
• If the source port has power, it will only display a live voltage reading within the operating range, 3-20V
DC. NOTE: Most USB ports deliver ~5V DC.
2. Connect the device being charged at output port. The display will show actual readings (FIG. 2).
TESTING MODE
NOTE: Disconnect external load to operate in this mode.
The ET910 can be used to test the maximum current that may be delivered from a powered USB port.
1. Connect the input connector to the USB port to be monitored.
• The display will turn on with Klein Tools logo screen and move quickly to the Default Screen (FIG 2).
• If the source port has power, it should only display a live voltage reading within the operating range,
3 – 20V DC. NOTE: Most USB ports deliver ~5V DC.
2. Press the Test Load button to select test load.
3. Testing loads under 10V will take 3 seconds; loads over 10V will take 1 second. The red LED remains lit
during testing. Once complete, the results will be displayed, including "PASS" or "FAIL". "PASS" indicates
that the USB port delivered up to the load current being tested. LED shuts off after testing is complete.
NOTE: Some USB power sources have integrated self-protection circuitry which the tester may trigger
or reset, shutting off the source output, resulting in the tester also shutting off, failing the test.
NOTE: If the tester heats up beyond operating temperature following multiple current measurements,
test mode will automatically deactivate and "HOT" will show on the display. If this occurs, disconnect all
external input and output devices until the tester returns to normal operating temperature.
4. To save the test data, see Data/Memory Storage and Recall in the FUNCTION BUTTONS section.
5. To move on to the next test, press and release the Test Load or Mode button. The "PASS" or "FAIL"
indicator will disappear. The tester is now ready for the next test. To switch to Monitoring mode, see
MONITORING MODE section. NOTE: "mAh" resets only when source is disconnected.
Be sure the tester is disconnected from both the input and output port. Use clean, dry, soft lint-free cloth
to wipe down the entire unit.
• Do NOT use abrasive cleaners or solvents.
Do not expose to high temperatures or humidity. After a period of storage in extreme conditions
exceeding the limits mentioned in the General Specifications section, allow the tester to return to normal
operating conditions before using.
