Safety & Warnings
Normal use of test equipment exposes users to a certain amount of danger from electrical shock. An electrical shock causing 10 milliamps of current to pass through the heart can stop most human heartbeats. Voltage as low as 35 volts dc or ac rms is considered dangerous and hazardous as it can produce a lethal current under certain conditions. Higher voltages are even more dangerous. Users should follow accepted practices to prevent contact with exposed high voltage and steer current away from the heart in case of accidental contact.
1. There is a danger of electrical shock from the DC output of the power supply because it can source 60 Vdc. Several test conditions using this power supply can create a high voltage shock hazard:
a. If the equipment under test is the “hot chassis” type, a serious shock hazard exists unless the equipment is unplugged or an isolation transformer is used.
b. If the equipment under test is “powered up” and uses high voltage in any of its circuits, the power supply outputs may be floated to the potential at the point of connection. High voltage may appear at unexpected points in defective equipment. Do not float the power supply output to more than 100 volts peak with respect to chassis or earth ground.
c. If the equipment under test is “off” and uses high voltage in any of its circuits under normal operation, discharge high-voltage capacitors before making connections or tests. Some circuits retain high voltage long after the equipment is turned off.
2. Use only a polarized 3-wire ac outlet to ensure the power supply chassis, case, and ground terminal are connected to a good earth ground, reducing the danger from electrical shock.
3. Do not expose high voltage needlessly. Remove housings and covers only when necessary. Turn off equipment while making test connections in high-voltage circuits. Discharge high-voltage capacitors after removing power.

Basic Usage and Operation Tips
Before using the Bk-precision-1711, ensure the device is powered on and the battery is sufficiently charged. Select the appropriate measurement mode using the rotary switch. Connect the test leads to the correct input terminals and attach the probes to the circuit or component under test. For accurate readings, avoid touching the metal parts of the probes during measurement. Use the Data Hold button to freeze the displayed value when needed. Always start measurements at the highest range if unsure of the expected values to prevent damage.
Troubleshooting and Maintenance
If the device displays erratic readings or fails to power on, check the battery and replace it if necessary. Inspect test leads for any signs of damage or wear, and replace them if faulty. Clean the device exterior with a soft, dry cloth; avoid using solvents or abrasive materials. If the multimeter shows “OL” on the display, it indicates an overload condition—reduce the input range or disconnect the test leads. Regularly calibrate the device as recommended to maintain measurement accuracy.
Safety Reminder
Always observe proper safety precautions when using the Bk-precision-1711. Do not exceed the specified input limits to avoid electric shock or damage. Use the multimeter only within its rated voltage and current ranges. Avoid measuring live circuits in wet or damp environments. Disconnect power to the circuit before connecting or disconnecting test leads whenever possible. Proper use and handling will ensure safe operation and prolong the life of your device.
