RCP-Multitester 449A

Model 449A has a DC sensitivity of 5000 ohms per volt for measuring low-current circuits where loading must be held at a minimum. A Germanium crystal rectifier permits AC measurement from 30 cps to 50 kc without temperature errors. The three-inch square meter is accurate to 2 per cent with metallized voltage multipliers of 1% tolerance used. Four AC and four current ranges up to 1000 ma, and four resistance ranges to 1 megohm are available through pin jack terminals on the front panel
