A measurement instrument for transmitting a signal for remote reading has a local readout (24) of a measured value of parameter being measured, interacting with a local two button (28, 30) calibration system, one button being used to set each end of a range of values to be transmitted by the remote signal, thus setting the calibration and span of the signal. The buttons may be used to enter currently displayed values, or by pressing both buttons at once, setting modes may be entered in which one button increases and the other increases a displayed value of a parameter to be entered. |
