Remote Sense Remote sense can be used to compensate for voltage drops up to 6 V (PVS60085/MR) or 10 V (PVS10005) due to resistance from test leads connected to your device under test (DUT), thus providing more accurate output voltage. The power supply is initially set up for local sense mode by default. Refer to the following sections for details of local and remote sense setup. Local Sense By default, the power supply is set up for local sense.
output is connected to the negative end (-) of the load. When this sensing mode is selected the wires connecting between DC outputs to the load must be as short as possible. The local sense is the default configuration with shorting bars connect between (+S) to (+) and (-S) to (-). DO NOT disconnect the wires if remote sense is not used. Doing so will cause erratic behavior and may damage the power supply under certain conditions.

Each step contains the voltage, current, time, and action. There are three types of actions that can be set: ON, OFF, and END. The ON action enables the current step and will be executed during operation.
Options Users also have the ability to utilize the REPEAT and NEXT PROG options. The REPEAT option allows the user to execute the same program as many times, continuously, as needed. The NEXT PROG option allows the user to select the next program to execute once the current program ends. Please be aware that REPEAT and NEXT PROG options are part of a program, so if one program’s NEXT PROG option is pointed to a previous program, the power supply will cycle these programs infinitely.
2. Use the rotary knob to select the setting of OFF or ON. 3. Use the buttons to move the cursor to the PROGRAM selection and use the rotary knob to select a program between 1-9. 4. Use the selection and press buttons to move the cursor to the EDIT . The following screen will be displayed: 5. As described previously, each step has the following parameters to be edited: step number, action, voltage, current, and time.

6 Troubleshooting Guide Below are some frequently asked questions and answers. Please check if any apply to your power supply before contacting B&K Precision. General Q: I cannot power up the power supply. - Check that the power cord is securely connected to the AC input and there is live power from your electrical AC outlet. - Verify that the AC power coming from the mains contains the correct voltage. The power supply can accept a specific range of AC input voltages. Refer to section 2.1.
Remote Control Q: I am trying to send the commands over USB/RS232, but it does not seem to respond. - Check that you are sending ASCII strings that are terminated with a CR (carriage return) and LF (linefeed) character. - For RS-232 and RS-485, check that the baud rate, parity, data bits, stop bit, and flow control settings match with the settings configured on the software interface. - For RS-485, check that the wires are correctly daisy chained between multiple units.
