Description
The TH3300 series includes single-phase digital power meters (TH3311, TH3312, TH3321, TH3331) with 4.3″ colour TFT display, fast DSP-based measurements of AC/DC quantities, power and energy integration, optionally with harmonic analysis and various current ranges for micro to large currents.Features
- 4.3″ 24-bit colour TFT LCD with English/Chinese user interface and numeric keypad/button operation
- True RMS measurement of voltage and current, selectable AC/DC component; measurement of power (P), apparent power (VA), reactive power (VAR), power factor, frequency, peak and peak values, energy (kWh)
- Automatic/manual measuring range: 4 voltage ranges (75/150/300/600 V) and 7-8 current ranges depending on the model:
- High accuracy: ±(0.15 % reading + 0.2 % range + 1 digit) at 45-75 Hz, ±(0.3 % + 0.2 % + 1 digit) at 75-400 Hz
- Sampling speed: up to 8 measurements/s (50 Hz), with harmonic analysis switched on 4 measurements/s
- Waveform and harmonic analysis (only with TH3312, TH3321, TH3331): List display and histogram up to 50th harmonic on/off, display in % or absolute value
- PLL technology for fast and precise synchronisation; adjustable line filter (5 kHz) for clean measurement
- Energy integration: time and kWh counter with start/stop/reset, up to 99,999 kWh and 9,999:59:59 h:min:s
- Comparison and bin functions with handle outputs for automation test benches (PASS/FAIL, lamps/relays, acoustic)
- Waveform display (voltage/current) for visual inspection of the signal
- Interfaces: RS232C/RS485, USB device/host for PC communication, HANDLER port for automation control
- Automation control, USB memory for logs and firmware upgrade
- Robust design, compact housing (235×105×360 mm), power supply 200-240 VAC, 50/60 Hz, ambient 0-40 °C, ≤80 % RH
- Flexible trigger modes: Internal, manual, external (HANDLER), bus (SCPI)
