7.2 Output Terminal
────────────────────────────────────────────────────
CAUTION
To avoid damage to this unit, do not shorten the output terminal or
input voltage.
NOTE
7.2 Output Terminal
(1) Analog output (
U
,
I
,
P
terminals)
Outputs ±5 V DCf.s. direct voltage for range.
Outputs simultaneously for voltage (U), current (I) and active power (P).
(2) Monitor output (
U
m,
I
m terminals)
Waveform output 1 Vf.s. for range.
Outputs simultaneously for voltage(Um), current (Im).
(3) D/A output (D/A OUT terminal)
Refer to Section 4.6, "Setting the D/A Output".
･ Output resistance of output terminals is about 100 Ω.
･ Always use the A.GND terminal (pin 1, 10, 14, 17, 22) for the common of
output terminal.
･ Analog output and D/A output voltage is ±5 VDC f.s. for each range. If
scaling or (PT, CT, SC) are being used, the value reached by multiplying the
range times scaling value becomes ±5 VDC.
･ When using the measuring range as auto ranging, analog output rate changes
as range changing. Be careful of making mistake for range conversion when
recording on the such line measuring value changes hard. In such
measurement we advice you to measure in fixed ranging.
･ The analog output response time is 0.2 to 0.3 seconds (FAST), 5 to 15
seconds (SLOW). Note that if there are fluctuations on the line being
measured which happen faster than the response time of the unit, errors in
the output voltage may occur.
When the response is FAST, analog output below 45 Hz includes ripple, and
cannot be used as a correct wave form.
･ Always use shielded cables for output and for external control.
