Installation / Setup
The installation and setup of the BK Precision Model 9110 power supply involve several key steps. Upon receiving the instrument, inspect it for any transit damage and verify that all supplied items, such as the power cord and instruction manual, are included. The power supply can operate on either 110V AC or 220V AC, and it is crucial to ensure that the voltage selector at the rear is set to the correct line voltage before connecting the power cord. If necessary, replace fuses according to the specified table for the appropriate line voltage range. The power fuse is located in a compartment below the AC input receptacle, and the power cord must be disconnected to access it. To power on the instrument, press the main power switch on the front panel. The unit will revert to the last setting used before it was turned off. Note that the 9-pin D-sub connector at the rear is for factory use only and the instrument does not offer a remote control interface.
Operation
The manual provides detailed instructions for basic usage of the BK Precision Model 9110 power supply. To set the voltage, press the voltage key to activate the voltage indicator, use the cursor keys to select the desired digit, and adjust its value with the knob. Similarly, to set the current, press the current key to activate the current indicator, use the cursor keys to select the desired digit, and adjust its value with the knob. The output can be toggled on or off by pressing the output key, with the OFF LED indicating when the output is turned off. The display will blink for 3 seconds to show the set values for volts and amps when the output is toggled. The power supply also features a key lock function to prevent unintended modifications, which can be activated by pressing the Shift key followed by the Lock key. Additionally, the manual describes how to set the Over Voltage Protection (OVP) and Over Current Protection (OCP) values, and how to enable or disable the key sound.
