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 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:1A) 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 USB-A, "M:1C" if USB-C). 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:1A or M:1C. 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 ET920 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.
GENERAL SPECIFICATIONS
The Klein Tools ET920 is a USB digital meter for both USB-A (Type A) and USB-C (Type
C) ports. It accurately and reliably measures and displays the USB port voltage, current,
capacity, energy and resistance simultaneously. It can function with any USB-A and most
USB-C ports that have the ability to deliver power. It requires no batteries, as it draws power
from the power source.
• Measurement Range:
Voltage: 3 to 20V DC, accuracy +/- 1% (+/- 2 Bytes)
Current: 0.05 to 3A (Type A), 0.05 to 5A (Type C), accuracy +/- 1% (+/- 2 Bytes)
Charge delivered: 99,999mAh MAX*
Energy delivered: 999Wh MAX*
Resistance: 400Ω MAX
Elapsed Time: Up to 999 hours, 59 min, 59 sec*

OPERATING INSTRUCTIONS
MONITORING MODE
NOTE: The USB-A input must be used with the USB-A output only. The USB-C input must be
used with the USB-C output only. This product does not function as a USB-C to USB-A adapter.
NOTE: USB-A and USB-C sides CANNOT be used simultaneously. The rst device connected,
whether USB-A or USB-C, will be the monitored 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 (USB-A or USB-C) to the USB power source that
needs to be monitored (FIG. 3).
• The LCD screen will turn on with Klein Tools logo screen and move quickly to the Default Screen
(FIG 2).
NOTE: For USB-C, a downstream device must be connected to turn on the ET920.
• 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 (FIG. 3). The display will
show actual readings (FIG. 2).
NOTE: "mAh" resets only when source is disconnected.
CLEANING
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.
STORAGE
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.
