HP-DJ is a multi-channel DAQ and analysis system for both static and dynamic measurements, offering synchronous sampling up to 5 kHz, flexible mixed inputs (DC/AC/strain), and high-accuracy signal conditioning for field and lab testing.
| Hybrid inputs per channel | Each channel can freely select DC, AC, and strain-gauge measurement types—no extra auxiliary equipment for true universal input. |
|---|---|
| Auto balancing / zeroing | Independent 16-bit DAC per channel enables full-range hardware auto-balance (zero). You can also set any balance point and manually set the zero point to meet test requirements without losing measurement range. |
| Synchronous parallel acquisition | High-stability conditioning + high-performance ADC; all channels sample, display, and save synchronously, up to 5 kHz maximum. |
| High accuracy & strong anti-interference | Each channel includes an independent high-precision 120 Ω bridge resistor, stable amplification/conditioning, and high-performance ADC for up to 0.2% test accuracy. |
| Adjustable excitation supply | 0–10 V / 400 mA adjustable excitation, software configurable per channel, 0.1% accuracy. |
HP-DJ is designed for test scenarios where you need mixed-signal acquisition (strain + voltage + current + temperature + displacement) with synchronized sampling and stable conditioning. Each channel can be configured independently, minimizing extra external modules and simplifying system setup.

Q1: What is “static & dynamic” in HP-DJ’s use case?
HP-DJ is suitable for static signals and low-to-mid speed dynamic signals (up to 5 kHz), including synchronized multi-channel acquisition.
Q2: Can I measure strain and 4–20 mA at the same time?
Yes. HP-DJ supports mixed inputs—strain bridges, voltage, and current (including 4–20 mA) within the same system configuration.
Q3: How do I synchronize with other equipment?
HP-DJ provides a SYNC terminal supporting level/edge recognition and an isolated 5V supply for synchronized triggering.
