| Mr.B:
Thanks tautech. I was not familiar with what looks like an old metal film resistor inside it. |

Is it a frequency counter? --- End quote --- ADP is for sensors matched to the unit, for temperature or current clamp for example. The sensors would use 1mV per whatever unit is being sensed. The DMM converts the mV level to the appropriate quantity and displays it; the Range button changes the conversion factor used. edit: I see that the question was already answered in the original post. |

It's a direct connection to the AD. 30 Mohms impedance. Pretty much same as in the old analogue meters, when you had direct access to the actual meter, wihtout any dividers. Here it is 400mV range, you can connect a calmp meter or anything, like a frequency-voltage converter. |

According to the marking on it, it's 156 Mohms. Probably sealed in a glass tube to protect from the environment, as it is such a high value. |
