1 Application
The N32P meter is a digital panel meter adapted to be fixed to the panel. The N32P
meters are designed to measure voltage, current, power and energy in A circuits. Voltage
and current measurement can be dome directly or using an external current and voltage
transformers. The parameters of the transformers used can be configured in the N32P
meter, so the indicated measuring values will correspond to the actual measuring values
on the primary of the transformers. The N32P meters also enable to measure only a single
parameter, e.g. only current, where the meter operation is synchronized with the current
signal waveform.
Additionally, the meter supports the programmable alarms with the delay activation and
deactivation function as well as a memory of the alarm event. The functionality of the
meter is complemented by a programmable analog output - RS-485 interface.
The user interface consists four buttons and the high contrast L D display with backlight.
Thanks to the two-line display, it is possible to set the selected unit, display simultaneously
the measuring value and the current time, as well as a clear and user friendly menu with
simultaneously visible the parameter name and its value.

5.3.1 How to change quantity of a selected parameter
To increase the value of the selected parameter, press the button . Pressing the
button will increases the currently set digit by 1 and after reaching the value 9, pressing
the button will set the value 0. After setting the required value of a digit, move to the next
digit by pressing the button . After setting the required parameter value, press the
confirm button to accept the entered value or the cancel button to cancel
the parameter change and return to the previous value of the parameter. It is possible to
change a sign of the entered value during setting the last digit (most significant).
There are three steps to change the floating point values. The first step is to set the digits
and a sign in accordance with the algorithm described above. The second step is set the
position of the decimal point after pressing the confirm button. The buttons
are used to set the position of the decimal point. After setting the decimal point position as
required, press the confirm button to move to the third step - setting the multiplier of kilo,
mega or no multiplier. Symbol of the multiplier value is shown on the left side of the

N32P-09 User's manual 15
display.
Entering an incorrect value of a given parameter causes that the new value is not
accepted and the parameter will automatically have the previous value.
To change the parameters other than numerical select the appropriate setting from the
parameter list using the buttons . After selecting the appropriate setting,
press the confirm button to download the setting or the cancel button to
return to the previous value and exit the parameter change mode.
