9. PROGRAMMING DATA
• Press the uu or vv button to step to the desired display screen.
• Press the uu and vv buttons simultaneously and hold for one second to enter the pro-
gramming mode. The header display will blink to indicate the meter has entered into the
programming mode.
• Press the uu button to increase the value of the setting data or the vv button to decrease
the value of the setting data.
• To save the selected value and to exit the programming mode, press the uu and vv
buttons simultaneously and hold for one second. The display will stop blinking and the
newly set data will be displayed.
• During the programming mode, if there is no button press for 15 seconds, the meter will
automatically exit the programming mode. The display will stop blinking and reset back
to its initial value.

10. PHASE VOLTAGE DISCONNECTION
• If any of the voltage measurement inputs is broken or disconnected, four dash bars will
appear on the corresponding phase voltage display.
11. PHASE SEQUENCE ERROR DETECTION
• L2 and L3 indicators will blink if the voltage sequence is wrongly wired.
• This feature is disabled if any of the voltage measurement inputs is broken.
• Select either single-phase or three-phase application
by pressing the or button.
• Set “3P” for three-phase application and “1P” for
single-phase application.
• The default setting is three-phase application.
• Set the CT primary value by pressing the uu or vv
button.
• The CT secondary is
fi
xed at 5A.
• The default value for CT primary is 5A.
• Set the power factor display mode by presing the
uu or vv button.
• Set “tPF” for true power factor and “dPF” for displace-
ment power factor.
• The default mode display is true power factor.
• There are two display modes available: rotational
mode or static mode.
• In rotational mode, the display screen will automatical-
ly scroll to the next display screen every 12 seconds
and rotate in a circular manner continuously. Only
measurement data is shown.
• In static mode, the display screen will stay at the latest
display screen permanently.
• By pressing the uu or vv button, set “YES” for
rotational mode and “NO” for static mode.
• The default display setting is rotational mode.
7. POWER UP LAMP TEST
• All display segments and indicators will turn on for one second during power up.
• Note that for DM36A and DM36V, only indicators corresponding to the respective mod-
els will turn on.

8. DATA VIEWING
• The measurement and setting parameters can be viewed by stepping through the vari-
ous display screens.
• Press the button once to step to the previous screen.
• Press the button once to step to the next display screen.
• Tables 3 and 4 show the list of items displayed for DM36.
• The items are displayed in the same sequence as per the tables when scrolled.
