Klein ET910 USB-A Power Meter with Built-In Test Loads
Klein ET910 combines USB-A power monitoring with selectable built-in loads. That lets you distinguish observing the current drawn by a connected device from deliberately applying a listed test load to a suitable USB power product description.
Specifications and included details
- 3–20V DC and 0.05–3A monitoring-mode current range.
- Built-in loads: 0.5A, 1A, 2A and 3A; no external load required.
- Monitoring up to 1000 hours for voltage, current, charge, energy and calculated resistance.
- Store and recall up to 10 readings.
Before ordering
Verify the product description's capacity and the meter's mode limits before applying a test load. Charge delivered and energy measured at USB are not automatically the connected battery's usable capacity. USB-C/PD negotiation support is not established here.
Product questions and answers
Do I need an external test load?
No. The meter lists built-in 0.5A, 1A, 2A and 3A loads.
Is monitoring the same as applying the 3A load?
No. Monitoring observes the connected setup; a selected test load intentionally draws the chosen current from a suitable product description.
Is displayed resistance a separate ohmmeter measurement?
The description identifies resistance as calculated, rather than establishing a standalone resistance test mode.
