Product overview
ZMPQ_LCD consolidates electrical measurements, waveforms, energy, temperature and events for distribution panels, buildings and factories. The local touchscreen and communication interfaces support operating review and system integration.
Functions and integration
Electrical and harmonic analysis
View phase and line voltages, current, power, power factor, frequency, phase angles and extrema, plus 2nd–63rd voltage/current harmonics and THD.
Waveform records
Live waveforms, freeze, snapshots, manual 10-second recording and alarm-triggered recording are supported. Six-channel recordings use a nominal 12.8kHz sample rate.
Energy and IO
Forward/reverse active and reactive energy, apparent energy, time-of-use and daily totals combine with six inputs, six relay outputs and 32 scheduling rules.
System access
Two RS485 ports provide Modbus RTU; Ethernet provides Modbus TCP, MQTT and BACnet/IP. CAN, logs and TF storage support integration and diagnostics.
Applications and operating workflow
Distribution monitoring
Review measurements and harmonics alongside equipment operating conditions.
Event investigation
Correlate alarms, snapshots and recordings with equipment switching and temperature measurements.
Building and factory systems
Map field data into supervisory systems through suitable industrial protocols.

Frequently asked questions
Is 0.1°C the measurement accuracy?
It is display resolution. Probe characteristics, installation and measurement conditions determine accuracy.
Does it replace billing meters or protection equipment?
It supports operating review and diagnostics. Billing and protection require equipment and design suited to those functions.
Is a browser required for local viewing?
No. The local touchscreen provides its own data and operation interface.
