Ken Kaarvik multimeter remote display project describes how to add a remote wireless display to specific digital multimeters (such as Fluke 17B) with a serial output using nRF24L01+ rf link. The transmitter and receiver units both uses Arduino (Trinket board). The receiving side also uses a 128×64 OLED to display the remote measurements.
