Notes:
[1]
All ac ranges except Auto-V LoZ are specified from 1 % to 100 % of range. Auto-V LoZ is specified from 0.0 V. Because inputs below 1 % of range are not
specified, it is normal for this and other true-rms meters to display non-zero readings when the test leads are disconnected from a circuit or are shorted
together. For volts, crest factor of 3 at 4000 counts, decreasing linearly to 1.5 at full scale. For amps, crest factor of 3. AC volts is ac-coupled.
Auto-V LoZ, AC mV, and AC amps are dc-coupled.

AC Volts Hz is ac-coupled and specified from 5 Hz to 99.99 kHz. Minimum input required above 50.00 kHz typically is >1.1 vac sine. Minimum input typical
and not specified. AC Amps Hz is dc-coupled and specified from 45 Hz to 5 kHz.

W>10 A unspecified.Duty cycle: >10 A to 20 A, 30 seconds on, 10 minutes off.

113 only: All
voltage ranges are specified from 60 counts to 100 % of range. Because inputs <60 counts are not specified, it is possible and
normal for this and other true-rms meters to display non-zero readings when the test leads are disconnected from a circuit or are shorted together. Crest
factor of 3 at 4000 counts, decreasing linearly to 1.5 at full scale.
[5]
113 only: After measuring voltage, a wait time of 1 minute is required to maintain accuracy of ohms, capacitance, diode test, and continuity.
