Pinout
We don't publish a pin table for this part: no official source we could verify gives one. Check the labels printed on your module, and see the notes below.
A meter has no header; see the Fluke user manual (110/113/114/115/117) for jack positions.
Build with it
Project ideas for the Fluke 115 multimeter. Each link opens Soldr with the prompt filled in; Soldr assigns the pins, checks power and shows how to wire every part.
- Current draw of a Pico project: Learning measurement task on a low-voltage circuit. The lowest current range is 6.000 A with 1 mA resolution and 1.0 % + 3 counts accuracy, so a 25 mA load reads within about +/- 3 mA; the meter suits loads of 100 mA or more better. Set the converter to 5.0 V first; place the meter in series only.
- Check the 5 V rail of a 7805 circuit: DC volts at 0.5 % + 2 is plenty to see if the output is inside the regulator's 4.8 V to 5.2 V range. Keep the load small so the 7805 stays cool.
- Measure the PWM frequency of an ESP32 pin: The frequency ranges run 99.99 Hz to 50.00 kHz at 0.1 % + 2. A 3.3 V logic output is inside the meter's voltage ranges; set a PWM frequency in that span.
Common mistakes
- Measuring current with the leads across a voltage source: the current inputs are fused (11 A, 1000 V) and must be placed in series with the load (source)
- Using it above its rating: 600 V to earth ground and CAT III 600 V; mains wiring needs a qualified person (source)
- Holding more than 10 A: above 10 A up to 20 A is allowed for 30 seconds on then 10 minutes off only (source)
Not covered by the official source
- Range and accuracy rows are from Table 6 of the Fluke users manual, which also gives safety, battery, display and temperature; the product page lists the same functions.
