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.
[2] AC Volts Hz is ac-coupled and specified from 5 Hz to 50 kHz. AC Amps Hz is dc-coupled and specified from 45 Hz to 5 kHz.

Basic Maintenance
Testing the Fuse (115 & 117 only)
To test the fuse:
1. Set the rotary switch to
Ω.
2. Plug a test lead into the v jack and touch the probe to the 10A jack, as shown in Figure 1.
If the display shows a resistance value in the range of that shown in Figure 1, the fuse is good.
If the display reads 0L, replace the fuse and test again.
If the display shows any other value, have the Meter serviced. See “Contact Information” earlier in this document.
