## 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 106/107 users manual for jack positions.

## Build with it
Project ideas for the Fluke 107 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 an Uno project](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20current%20draw%20check%20of%20an%20Arduino%20Uno%20with%20a%20BME280%20sensor%20and%20an%20LCD%20using%20a%20Fluke%20107%20in%20series%20with%20the%20supply): Learning measurement task on a low-voltage circuit. The lowest current range is 4.000 A with 1 mA steps, so small currents read coarsely. Place the meter in series only.
- [Measure the PWM frequency of an ESP32 pin](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20PWM%20frequency%20check%20using%20the%20frequency%20function%20of%20a%20Fluke%20107%20on%20an%20ESP32%20output%20pin): The frequency function covers 10 Hz to 100 kHz at 0.1 % + 3 (107 only). A 3.3 V logic output is inside the voltage ranges.
- [Component check bench for capacitors and an LDR](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20parts%20check%20bench%20with%20a%20Fluke%20107%20to%20measure%20100%20nF%20capacitors%20and%20an%20LDR%20in%20light%20and%20in%20shadow): The 500.0 nF range covers a 100 nF part (2 % + 5 plus lead capacitance); the resistance ranges cover the LDR. Remove parts from circuits first.

## Common mistakes

- Measuring voltage with the leads in the current jack: the A input has an 11 A fuse and very low resistance, so use it in series only ([source](https://media.fluke.com/8eaf269b-51d3-435f-9e69-b10800c0e4df_original%20file.pdf))
- Using it above its rating: 600 V to earth ground and CAT III 600 V; mains wiring needs a qualified person ([source](https://media.fluke.com/8eaf269b-51d3-435f-9e69-b10800c0e4df_original%20file.pdf))
- Holding 10 A too long: the 10 A range allows under 7 minutes on and 20 minutes off at 25 C to 40 C ([source](https://media.fluke.com/8eaf269b-51d3-435f-9e69-b10800c0e4df_original%20file.pdf))
