ABS Sensor readings

Hi All, does anyone know what the ohm range readings for the ABS sensors should be?

I removed the instrument cluster to replace a bulb and discovered that some monkey had removed the ABS and BAS/ESP bulb holders!
I waiting for new holders/bulbs to arrive and thought I would check the front sensors first.
I think my multimeter is toast though...

Thanks in advance.

Just to add, the r/h/f sensor gives me a reading of 2348 Mohms on one tester and about 1121 on another
