I. Application and Features:
The DC Current Standard Source HGZA300 is an intelligent DC current standard source. This instrument features linear power supply output for DC current with low DC ripple, utilizing a comparator sampling method to ensure measurement accuracy.
The display is an LCD touch screen with a 6 1/2-digit dynamic display outputting actual values and featuring percentage display. The full scale value of the meter can be set arbitrarily, and the amplitude adjustment is controlled by buttons to adjust the output value size.
II. Main Features:
2.1 5 1/2-digit (6 1/2-digit) LCD digital display, showing output values and percentages simultaneously.
2.2 Utilize button control for adjusting the output current. The keyboard control ranges are 10% scale, 1% scale, 0.1% scale, 0.01% scale, and 0.001% scale.
2.3 Within the range displayed on the panel, any required range can be set arbitrarily.
2.4 The external control regulator can remotely control the increase or decrease of output quantity.
2.5 Current Output Range: 0～300A
2.5 Output overload protection with automatic shutdown and manual reset.
Section 3: Technical Performance:
3.1 Stability: < 0.01% of full scale / minute
3.2 Output Current Range:
0～75A、0～150A、0～300A
3.3 Output Current Range and Accuracy (at 23℃±2℃, output value greater than 10% of the range)
