Before applying power to this instrument: • Read and understand the safety and operational information in this manual. • Apply all the listed safety precautions. • Verify that the voltage selector at the line power cord input is set to the correct line voltage.
Electrical Power This instrument is intended to be powered from a CATEGORY II mains power environment. The mains power should be 115 V RMS or 230 V RMS. Use only the power cord supplied with the instrument and ensure it is appropriate for your country of use. Ground the Instrument To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical safety ground. This instrument is grounded through the ground conductor of the supplied, three-conductor AC line power cable.
Do not operate instrument if damaged If the instrument is damaged, appears to be damaged, or if any liquid, chemical, or other material gets on or inside the instrument, remove the instrument’s power cord, remove the instrument from service, label it as not to be operated, and return the instrument to B&K Precision for repair. Notify B&K Precision of the nature of any contamination of the instrument.
Do not substitute parts that are not approved by B&K Precision or modify this instrument. Return the instrument to B&K Precision for service and repair to ensure that safety and performance features are maintained. For continued safe use of the instrument • Do not place heavy objects on the instrument. • Do not obstruct cooling air flow to the instrument. • Do not place a hot soldering iron on the instrument. • Do not pull the instrument with the power cord, connected probe, or connected test lead.

Press thru and to select a preset voltage and current value. to adjust preset voltage and current values. within 3 seconds to confirm or press to exit program setting. 5.2 Setting Timed Program The unit can be programmed to operate up to 20 timed subprograms (0-19 STEP as shown in the display).
Maintenance 6.1 Recalibration The purpose of recalibration is to reduce the difference between the set values and the displayed values on the LCD display. Recalibration is only required when this difference is greater than 0.1 V for voltage or -0.01 A / +0.02 A for current. 6.2 Troubleshooting Keypad and Dial do not work Check key lock symbol for lock state, unlock unit by pressing then lem persists.
PC Software Control and Installation The PC software provides remote communication, data logging, front panel emulation, and timed programming capabilities using the USB or RS-485 interfaces. The software supports Windows 7, 8, 8.1, 10. Note: Do not connect both USB and RS-485 simultaneously. 7.1 USB Driver Installation Remote communication using USB requires the installation of the CP210X USB virtual COM driver available for download at bkprecision.com. The USB driver is only required for Windows 7, 8, 8.
