2. Rotary selection switch: OFF, V~ , A~, V , A
3. Lever/trigger: Opens or closes jaws
4. HOLD:
Freezes last measured value on display (excluding bar graph)
Zeroes instrument during DC measurements
5. Input: Color-coded voltage input connectors
6. Display: Dual liquid crystal display, 4-digit 10,000 counts
7. MIN/MAX:
• Selects Record mode for A, V, %THD, Individual harmonics,
%DF, CF, THDF, Ripple and Peak (+/-)
• Accesses the following functions: MAX, MIN, AVG
8. SMOOTH: 3-sec averaging for easy readings on fluctuating signals
9. Hz: Selects frequency measurement (A or V input)
10. RANGE:
Selects Auto or Manual Ranging measurement ranges (A or V)
11. HARM: Accesses (in A or V) the following measurement modes:
• %THD (Total Harmonic Distortion referenced to the fundamental)
•
%DF (Distortion Factor - Total Harmonic Distortion referenced to RMS)
•
CF (Crest Factor)
• K Factor (Transformer Derating Factor [A~])
12. : Hdc, H 01-H 25: Individual Harmonics (from dc - 25th order)
and +/- Peak
13. Shift: Yellow Shift key selects different measurement modes dependent
upon rotary switch position:
