Frequency
Lower than 0.4% f.s. becomes out of
range. (Approx. 6.5 V)
･ In 500 Hz range, 500 Hz is 100%
･ In 100 kHz range, 100 kHz is 100%
･ During "-----Hz" display, the output
of the previous display is maintained.

Figure 5 D/A Output of Frequency
Figure 6 D/A Output of Integration (Example for active power integration)
NOTE
(1) When the integrated value equals a multiple of "the measurement range multiplied by the set
integration time", the D/A output of the integration value becomes 5 V. For example, if the
measurement range is 300W and the integration time is set to 24 hours, when the integrated
value is 7.2 kWh (300 x 24), 14.4 kWh (300 x 24 x 2), 21.6 kWh (300 x 24 x 3)… its the D/A
output will be 5 V (when it is a multiple of -7.2 kWh, the D/A output will be -5 V).
(2) When integration has started, D/A output begins to change. When integration has stopped,
the last D/A output is maintained. When integration has restarted, D/A output begins to
change again.
(3) When the integration value is reset, D/A output returns to 0V.
(4) When the integration value exceeds ±5 V, D/A output returns to 0V and then begins to
change again.
(5) If the displayed value is held (by the HOLD function) during integration, the D/A output will be
held, too. When the display HOLD is cancelled, D/A output begins to change again according
to integration value.
･ Maximum output is 130% (±6.5 V) of range.
･ In the case of plus out of range, about 6.5 V are outputted, for minus out of range, about -6.5 V
are outputted.
･ During holding or averaging, the value displayed is outputted.
･ D/A exchanging rate is about five times/second. There is a filter in the output circuit, and the
response time is about 0.5 seconds.
･ When integrating by external control, the set range multiplied by integrate time will be 5 Vf.s.
