Selecting the Number of Displayed Digits
You can select the maximum number of displayed digits for V (voltage), A (current), W
(active power), VA (apparent power), var (reactive power), PF (power factor), VHz
(voltage frequency), AHz (current frequency), and harmonic measurement values
(voltage, current, active power, power factor, and relative harmonic content). The
initial setting is Hi.
• Hi
The number of displayed digits is set to 5 (99999).
• Lo
The number of displayed digits is set to 4 (9999).
Note
• The actual number of displayed digits may be smaller than the maximum number of
displayed digits depending on the combination of the voltage range and current range and
the automatic digit carrying operation.
• Values such as Vpk (voltage peak), Apk (current peak), phase angle, efficiency, crest
factor, four arithmetic operations, average active power, integrated value, elapsed
integration time, and harmonic measurement values (harmonic distortion and phase
angle) are not affected by the number of displayed digits set in this section. For details,
see the sections describing each item.
Selecting the Display Update Rate
You can select the display update rate of the measured or computed results shown on
the display from the choices below. The UPDATE indicator blinks in sync with the
selected display update rate. You can increase the display update rate to measure
the load power that changes relatively fast or decrease the rate to measure the power
of a signal with a relatively long period. The initial setting is 0.25 s.
0.1 s, 0.25 s, 0.5 s, 1 s, 2 s, and 5 s
Note
The display update rate of 0.1 s appears as a possible selection when the harmonic
measurement function is ON. However, it cannot be selected. If the display update rate had
been set to 0.1 s when the harmonic measurement function was OFF, the rate is changed to
0.25 s when you turn on the harmonic measurement function. In this case, the display update
rate remains at 0.25 s even if you turn the harmonic measurement function back OFF.
