Energy test by test port

3.3.
The meter has an own test port. For this test it is not necessary to set the meter in the calibration
mode.
For this test is a special "energy- test- cable" available (code. no. 3024799)
The wires are defined as:
Pulse output:
Volume pulse input:
GND:
Note: The meter needs ~1min to activate the adapted cable
a. Input:
Volume pulses has to be time continuously
f
≤ 100 Hz
max
Passive Pulse:
R
≤ 10 kΩ (internal Pull-UP U
max
b. Output:
Energy pulses as burst
Pulse duration has a dynamic adaption on the frequency
f
≤ 800 Hz
max
U
. ≤ 60 V
max
I
