ENGLISH
INSTRUCTION MANUAL - USB DIGITAL METER - TYPES A AND C
GENERAL SPECIFICATIONS
The Klein Tools ET920 is a USB digital multi-meter for both USB Type-A and
Type-C ports. It simultaneously measures and displays the USB port voltage,
current, capacity, energy, and resistance. It can function with any USB Type-A
and most Type-C ports that have the ability to deliver power. It requires NO
batteries and uses minimal power from the power source to function, ensuring
accurate and reliable readings.

FUNCTION BUTTONS (FIG. 1)
MODE BUTTON 5 (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
Enhanced Screen.
• From the default screen, pressing and releasing twice will switch to the
Memory Screen.
• When in the Memory Screen, repeated pressing will cycle through all 10
memory locations, beginning with M:1.
2. Data/Memory Storage and Recall:
• 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. The memory location will reflect the connector type in use
when the data was stored (i.e. "M:1A" if Type-A, "M:1C" if Type-C).
3. Memory Reset:
• 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.

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. (Display will read "OVERLOAD" in this condition)
• 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.

OPERATING INSTRUCTIONS
MONITORING MODE
NOTE: Type-A and Type-C sides CANNOT be used simultaneously. The first device
connected, whether Type-A or Type-C, will be the primary source.
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 one of the ET920's input connectors (Type-A or Type-C) to the USB port that needs to
be monitored.
• The LCD screen 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. Connect the device being charged to the output port of the ET920. The display will show actual
readings (FIG. 2).
3. User can monitor in either default or enhanced screens. Information displayed will differ (FIG. 2).
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.
DISPOSAL / RECYCLE
Do not place equipment and its accessories in the trash. Items must be properly disposed
of in accordance with local regulations. Please see www.epa.gov or www.erecycle.org for
additional information.
