1. Fixed for current current voltage and off output:
1. Carefully check whether the AC input voltage is consistent with the input voltage of the product, and ensure that the connection is correct.
2. Place the electronic load in the closed state and connect the measured source (note the positive and negative polarity).
3. Open the rear panel switch, then the LCD is on, and the LCD screen displays the following interface (press MODE to switch):
4.Select the required mode and press the encoder, at this time the voltage / current / resistance / power value of the last flicker, rotate the the encoder can change, press the encoder to change the carry, no action 5S to save to the current required value, click LOAD can directly pull the load.as illustrated in following figure:
5.In the case of load pulling, select the encoder to switch to display W / WH / AN / S, press the INTEGRATOR integral button to start timing and calculate WH / AH / S, and press the INTEGRATOR integration button again to stop and rotate the encoder to view the current WH / AH / S and other parameters.
6.Press the SHORT short circuit button, can directly pull the measured source to the maximum current or the maximum current of the load, in the load case SHORT is the priority.
2. Fan speed introduction
DH-801 has the function of controlling fan speed and overtemperature protection. When the output is started, the fan starts and the air volume changes automatically with the power or current changes.
