DIGITAL MULTIMETER

Sample make/model: FLUKE · 179

DIGITAL MULTIMETER

Description

The primary purpose of this PT is to provide an opportunity for participants to demonstrate proficiency in the calibration of a 3.5-digit digital handheld multimeter. This PT kit contains a Fluke 179, 3.5 digit digital multimeter.

How this PT is scored

Each reported value is compared with the Lake Balance reference value using the En number, which accounts for both your expanded uncertainty and ours. Results are available in the customer portal. See Multimeter proficiency testing, all calibration PT programs, and our ISO/IEC 17043 certificate & scope.

Sample instructions

To complete this PT you will need a standard capable of sourcing DC Voltage, AC Voltage, DC Current, AC Current, Resistance, Capacitance, Frequency, and Thermocouple Simulation.

  1. Source 50.0 mV DC into DMM-112 and record voltage reading and uncertainty on the Data Reporting Sheet.
  2. Source 200.0 V DC into DMM-112 and record voltage reading and uncertainty on the Data Reporting Sheet.
  3. Source 500.0 mV @ 45 Hz AC into DMM-112 and record voltage reading and uncertainty on the Data Reporting Sheet.
  4. Source 200.0 V @ 1 kHz AC into DMM-112 and record voltage reading and uncertainty on the Data Reporting Sheet.
  5. Source 3.00 mA DC into DMM-112 and record current reading and uncertainty on the Data Reporting Sheet.
  6. Source 250.0 mA DC into DMM-112 and record current reading and uncertainty on the Data Reporting Sheet.
  7. Source 3.00 mA @ 45 Hz AC into DMM-112 and record current reading and uncertainty on the Data Reporting Sheet.
  8. Source 250.0 mA @ 1 kHz AC into DMM-112 and record current reading and uncertainty on the Data Reporting Sheet.
  9. Source 500.0 Ω into DMM-112 and record resistance reading and uncertainty on the Data Reporting Sheet.
  10. Source 250.0 kΩ into DMM-112 and record resistance reading and uncertainty on the Data Reporting Sheet.
  11. Source 9.50 µF into DMM-112 and record capacitance reading and uncertainty on the Data Reporting Sheet.
  12. Source 5 V @ 10.00 kHz into DMM-112 and record frequency reading and uncertainty on the Data Reporting Sheet.
  13. Source 100.0 °F Type K into DMM-112 and record temperature reading and uncertainty on the Data Reporting Sheet. Allow 3 minutes before taking a reading to allow thermal EMFs to dissipate fully.
  14. Email results and your uncertainty budget to proficiency@lakebalance.com
  15. After you've received your completed test results, return to Lake Balance Calibration Solutions.
