The dial interface follows traditional multimeter design conventions, though some users report difficulty reading the dial markings in low-light conditions. The switch positions are clearly marked, but the labeling could benefit from larger, more contrasting text for improved visibility.
Physical Dimensions and Portability
While marketed with “pocket” in its name, the actual dimensions make this more of a toolbox-sized instrument rather than truly pocket-portable. The unit is described as larger than pocket-size, particularly when test leads are attached. However, its lightweight construction makes it highly portable for toolbox storage and field use applications.
Performance Analysis
Voltage Measurement Accuracy
The voltage measurement capabilities represent the multimeter’s most reliable function across user reports. Most users report satisfactory accuracy for DC voltage measurements, particularly when testing automotive batteries, household batteries, and basic circuit voltage verification. The instrument appears to maintain consistent readings with minimal drift over time.
However, accuracy issues have been reported by some users, with specific instances of readings being 1.5-2V higher than actual values, and some extreme cases reporting readings 7-9 volts higher than true values. These accuracy problems appear to be unit-specific quality control issues rather than systematic design flaws, as many users report excellent accuracy when compared against reference meters.
For AC voltage measurements, the multimeter performs adequately for basic household electrical testing, successfully identifying 110V and 240V circuits. Users have successfully employed the device for testing wall outlets, light fixtures, and basic AC circuit verification.
Current Measurement Performance
Amperage measurement capabilities receive mixed reviews from users. The multimeter successfully measures basic current draw applications, such as automotive parasitic draw testing and general DC current verification. However, some users report inconsistent readings and unusual behavior where measurements start at one value and drift to zero, suggesting potential internal calibration or component quality issues.
The absence of a dedicated milliamp (mA) port limits the instrument’s precision for low-current measurements, restricting its usefulness in sensitive electronic applications where precise current measurement is critical.
Resistance and Continuity Testing
The resistance measurement function shows the most significant quality control variations among units. While some users report accurate ohm readings suitable for basic electrical work, others experience severe issues including:
