Thank you for purchasing the DPM680 Digital
Power Meter. This multifunction power meter
features a user-friendly colour graphical and
touch button interface. It’s primary function is for
measuring the following parameters:
• True RMS phase (LN) and line (LL) voltage.
• True RMS phase and neutral current.
• Active, reactive and apparent power.
• Active, reactive and apparent energy.
• Total and displacement power factor.
• Frequency.
• Voltage and current harmonics.
• Voltage and current total harmonic distortion (THD).
• Positive, negative and zero sequence voltage
and current.
• Current (thermal) demand for phase current.
• Power demand for active, reactive and apparent power.
• Time stamped maximum and minimum voltage,
current, power factor, frequency and power.
• Time stamped maximum current and power
demands.
It’s large colour graphics LCD also displays:
• Scalable voltage and current waveforms
• Voltage and current harmonic spectrums up to
the 32nd order
Introduction

How To usE THis Manual
For installation instruction, the Installation chapter
2 should be read carefully.
The OVERVIEW page & MAIN MENU and
Password Authentication sections of the Meter
Operations chapter 3 cover the common steps
before jumping to any parameter page. The tree
diagram shown in Fig 1 shows the menus, sub
menus, pages and sub pages to navigate through
before reaching the page of interest.
Please refer to the Table of Content to jump to
the operation details in the Meter Operations
chapter 3. Chapter 6 on Troubleshooting
Guide can be used stand-alone. For DPM680,
chapter 4 deals with the Webpage Operations.
Finally, chapter 5 on the Modbus Operations
should be used in conjunction with the DPM680
Modbus communication Manual that can be
downloaded from the www.itmikro.com website.
Information on calculation methods are given in
Appendix B.
