The Bk Precision Model 310 Digital Milli-Ohm Meter manual covers setup procedures such as inspecting the device for damage, checking battery status, and ensuring proper current regulation and voltage measurement before use. It also provides operational instructions, including selecting measurement ranges, initiating tests, and interpreting display readings, as well as troubleshooting guidance like replacing fuses and addressing over-temperature conditions.
Manual Overview
The Bk Precision Model 310 Digital Milli-Ohm Meter manual provides detailed guidance on troubleshooting, diagnostics, calibration, and board-level adjustments. For troubleshooting, the manual emphasizes checking battery status and current regulation by connecting leads to specified terminals and observing LED indicators. Error diagnostics involve monitoring the R and R.Leds; if lit, they indicate issues such as over-range or high resistance, which can be resolved by adjusting the resistance range. Calibration involves ensuring the current regulation is correct by shorting test leads and verifying LED status. The manual advises on board-level guidance by detailing connections for current and potential terminals, ensuring accurate measurements. The meter is protected by fuses and a crowbar circuit, which activates under high voltage conditions to prevent damage. Users are instructed to perform preliminary checks, including battery replacement and verifying voltage measurements, before use. The manual stresses the importance of following safety precautions, such as ensuring circuits are de-energized before testing and using undamaged test leads.
Quick Issues Covered
- Diagnose current regulation issues with R_LED indicator.
- Identify over-voltage conditions via R_LED and display readings.
- Use schematics for circuit tracing and troubleshooting.

Safety & Warnings
Read the User’s manual carefully and completely before using the instrument. Fully understand the instructions before using this product. Follow the instructions for every test. Take all the necessary precautions. Do not exceed the limits of this instrument. The circuit to be tested must be de-energised and isolated before connections are made to it. Do not use test leads, probes or crocodiles/alligators clips that are dirty, damaged or have broken or cracked insulation. Such accessories should be removed and repaired immediately. Always disconnect the test leads before replacing any fuse. Always replace the fuse with the type specified and ensure that they are correctly fitted. Double check the switch settings and leads connections before measuring. Make a sketch to ensure proper operation and principle of measurement is correct and well understood. Do not touch any exposed wiring, connections or other “live” parts of an electrical circuit. If in doubt, check the circuit first for voltage before touching it. This instrument should only be used by a competent, suitably trained person who understands fully this test & measurement procedure. Warning, risk of electric shock. Caution, refer to this manual before using the Meter.
