Notes:
[a] The range for both primary and secondary display are corresponding to the higher range of two displays (autoranging mode, while the
range of secondary display are the same as the primary displays (manual range mode).
[b] The frequency measurement corresponding to the current input signals; other measurements are corresponding to the voltage input
signals.
[c] In dual display mode, users are recommended to measure the resistance up to 1 MΩ.
[d] At 12 A range, manual range mode is selected by default.
[e] Measurable with non-guaranteed accuracy.
[f] Autoranging mode by default.
[g] The voltage or current range of the frequency function follows the voltage or current range of the other function.
NOTE
In dual display mode, the
The multimeter has an increased key response time (0.6 s to 1 s) when in dual
display mode. You may need to press the selected key until the multimeter
responses.
