YOKOGAWA WT210 User Manual

5-8 IM 760401-01E
Explanation
Displaying the Peak Value
is displayed at the front of display C. The peak value of voltage is displayed when
the unit display is V; the peak value of current is displayed when the unit display is A.
• Maximum display: 9999
• Unit: Voltage peak value V, current peak value A
• Prefixp: m, k, or M
The absolute values of the plus and minus sides of the displayed values for Vpk
(voltage peak) and Apk (current peak) are compared, and the larger of the two is
displayed. For example, if the plus side peak is +100.1 Vpk and the minus side peak
is –100.2 Vpk, 100.2 Vpk is displayed for the peak value.
Efficiency (WT230 only), Crest Factor, Four Arithmetic Operation and Average
Active Power Display
When
is displayed at the front of display C, the efficiency, crest factor, four
arithmetic operation value, or average active power specified in sections 4.9 to 4.12 is
displayed.
• Maximum display (display range)
• Efficiency: 0.00 to 999.99 (%)
• Others (crest factor, four arithmetic operations, and average active power): 9999
• Unit
• Average active power: W
• Others (efficiency, crest factor, and four arithmetic operations): No unit
• Prefix
• Four arithmetic operations and average active power: m, k, or M
• Others (efficiency and crest factor): No prefix
Note
Depending on the computed item, computation overflow or no data may be indicated rather
than a value.
Efficiency
If the denominator of the equation for deriving the efficiency is less than or equal to
0.0001% of the rated range, computation overflow ( --oF-) is indicated.
Crest factor
• If the RMS value is less than or equal to 0.5% (less than or equal to 1% if the crest
factor is set to 6) of the rated range, computation overflow ( --oF-) is indicated.
• If the measurement mode is VOLTAGE MEAN or DC, no data ( -----) is indicated.
Four arithmetic operation
• If the display A function is indicating the elapsed integration time (TIME), the computed
result indication is no data ( -----).
• If the value of the display B function is less than or equal to 0.0001% of the rated
range, computation overflow ( --oF-) is indicated.
