12 Operation
12.1 Consumption indication
There is a red LED on the front panel which indicates the consumption measured by the meter.
When power is consumed, the LED will flash. The faster the LED flashes, the more power is
consumed. For this meter, the LED will flash 1000 or 2000 times per kWh, see section 0. (Please
take note of the following: the meter has a green backlight, which can also be seen near the red
LED, please don’t get confused).
12.2 Reading the meter
The PRO1 series meter can be delivered with either a digital or mechanical register. See the
version numbering in section 1.3.
12.3 Mechanical register
The PRO1TE series energy meter is equipped with a mechanical 5+1 register which is used to
record consumption and can’t be reset to zero. Five decimals are marked with white color and one
decimal is marked with red. The reading accuracy is 1/10 kWh. For this meter, the LED will flash
1000 or 2000 times per kWh depending on the version of the meter, see section 0 for details.

® 2011 - 10 - For the SOP number see section 15 PRO1 V11.xxx
12.4 Digital register
The PRO1D series energy meter is equipped with a 5+2 digit LCD which is used to record
consumption and can’t be reset to zero. The display has 5 digits before and 2 decimals after the dot
on the display. The reading accuracy is 1/100 kWh. For this meter, the LED will flash 1000 or 2000
times per kWh depending on the version of the meter, see section 0 for details.
12.5 Pulse output
The energy meter is equipped with a pulse output which is optically isolated from the inside circuit.
It generates pulses in proportion to the measured consumption for purpose of remote reading or
accuracy testing. The pulse output is a polarity dependent, open-collector transistor output
requiring an external voltage source for correct operation. For this external voltage source, the
voltage (Ui) should be lower than 27V DC. The maximum switching current (Imax) is 27mA. To
connect the impulse output, connect 5-27V DC to connector 20 (collector), and the signal wire (S)
to connector 21 (emitter). The pulse output depends on the version and is either 1000 or 2000
impulses per kWh. See section 0 for details regarding the impulses per kWh.
