B&K 290 VOM calibrate procedure needed.
My B&K 290 meter reads low on ac & dc volts.Can anyone share the calibration
procedure? Resistance is close but a large rezero adj is needed when switching between low & high power resistance It has the following pots + and - DC Cal AC cal Bias adj and Bal Adj (I have no idea about these) One unlabled pot mounted on the range switch. John |

John Just a guess, but Bias = zero adjust, Bal = Neg/Pos equality. -- N |
