SET UP
1. Enter the set up mode by pressing both the simultaneously, the display keys should be showing the
rmware version. The rmware version is read only and cannot be changed.
2. Press the
key again to show
then set the desired
RS485 address using the 99.
key. The address can be set from 0 to
3. Press the
key again to show
then set the
desired baud rate using the 1200, 2400, 4800 or 9600.
key. The selectable baud rates are:
4. Press the
key again to show
then set the PT
using a combination of the
key to change the digit and the
to move to the next digit. The PT can be set from 1.00 to 4.00, 100 or 200.
5. Press the
key again to show
then set the CT ratio
using a combination of the
key to change the digit and the
to move to the next digit. The CT ratio can be set from 1 to 1000. For the standard 5A model, set the CT ratio accordingly. Example 1: using a CT with ratio 100:5, set the CT ratio to 20. Example 2: using a CT with ratio 200:1, set the CT ratio to 200. Caution: For the dedicated CT model, the ratio has been factory set and should not be changed, changing this value may result in an incorrect or inaccurate reading.
6. Press the
key again to show
. This shows the
model type of the PM210. Yes means that the meter is the standard 5A model, no means that the meter is the dedicated CT model. Caution: Do not change this value, this is factory set, changing this value may result in an incorrect or inaccurate reading.
7. Press the
key again to show
. This shows the wiring
type, 3 sets the meter to recognize the wiring as 3 phase 3 wire, 4 sets the meter to recognize the wiring as 3 phase 4 wire.
8. Press both the
simultaneously to leave the setting mode
and return to the normal display mode.
