Setting up pulse output rate
The meter is equipped with two pulse outputs (forward and
reverse) which are optically isolated from the inside circuit. The
meter 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 which requires
an external voltage source for correct operation. For this external
voltage source, the voltage (Ui) should be less than 27
V DC. The maximum switching current (Imax) is 100 mA. To
connect the impulse output, connect 5 – 27 V DC to connector
18/20 (collector), and the signal wire (S) to connector 19/21 (emitter).
To change the pulse output (S0) rate, follow these steps:
- Scroll with the buttons to Program mode 3 (Pro-3).
- Hold the up-arrow button for 3 seconds to enter the menu.
- Enter the 4 digit password (default: 0000): scroll with the buttons and select each digit 0 – 9, hold the up-arrow button for 3 seconds to confirm each digit.
- Scroll to S0 output (S0/S) page.
- Hold the up-arrow button for 5 seconds to enter program mode.
- When the value starts blinking: select 10000 / 2000 / 1000 / 100 /10 / 1 / 0.1 / 0.01.
- Hold both buttons for 3 seconds to confirm the new setting.
- The LCD displays OK when the setting is confirmed.
