When testing small currents, for example, currents less than 10 mA, my DL3021A does not apply the correct current until it reaches 8 or 9mA, then when dialing back to 0mA it seems to work until you reach 0mA then the trouble starts over.For example, setting the load to 0mA applying a source voltage 3.3V shows: current setting read value (manually increasing by 1mA)=================0.000A 0.0021A0.001A 0.0022A0.002A 0.0023A0.003A 0.0023A0.004A 0.0023A0.005A 0.0024A0.006A 0.0024A0.007A 0.0025A0.008A 0.0025A0.009A 0.0095A |
