## 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 110 multimeter. Each link opens Soldr with the prompt filled in; Soldr assigns the pins, checks power and shows how to wire every part.

- [Battery pack voltage under load](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20battery%20pack%20health%20check%20measuring%20a%209%20V%20six-cell%20AA%20pack%20with%20a%20Fluke%20110%20while%20it%20powers%20an%20Arduino%20Uno%20and%20an%20LCD): DC volts only on a 9 V pack, well inside the 600 V rating. Compare readings with and without the load.
- [A 5 V regulator output check with a Fluke 110 measuring a 7805 regulator fed from a 9 V six-cell AA pack](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%205%20V%20regulator%20output%20check%20with%20a%20Fluke%20110%20measuring%20a%207805%20regulator%20fed%20from%20a%209%20V%20six-cell%20AA%20pack): A 0.5 % + 2 DC volts reading shows whether the output is inside the regulator's 4.8 V to 5.2 V range. Keep the load small so the 7805 stays cool.
- [Set a buck converter to 5.0 V](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%205.0%20V%20setup%20check%20where%20a%20Fluke%20110%20verifies%20a%20buck%20converter%20module%20before%20it%20powers%20an%20ESP32%20board): Adjust the converter with no load, read it with the meter, then connect the ESP32 board. This protects the 5 V input of the board.

## Common mistakes

- Looking for a current jack: the 110 has no amps input, so it cannot measure circuit current ([source](https://media.fluke.com/5e1db354-3a6e-49cf-9edd-b10800c0e608_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/5e1db354-3a6e-49cf-9edd-b10800c0e608_original%20file.pdf))
- Reading outside the rated conditions: accuracy is specified at 18 C to 28 C ([source](https://media.fluke.com/5e1db354-3a6e-49cf-9edd-b10800c0e608_original%20file.pdf))

## Not covered by the official source

- The 110 has no capacitance or frequency function: Table 6 lists capacitance for the 113, 115 and 117, and frequency for the 115 and 117.
- All values are from the Fluke 110/113/114/115/117 users manual (Table 6 and the general specifications); only rows whose model column includes the 110 are used.
