AT 33 IND™
Two tests in one. The instrument can be used in two modes: static and dynamic. Both quickly collect data in the auto mode and there is no need to operate a lot of difficult to understand buttons.
ALL-TEST PRO 31™
The AT31™ will measure impedance(Z), phase angle (Fi), current / frequency response (I/F), insulation to ground resistance (500V or 1000V and measure to 500 meg-ohm), will perform a quick pass/fail rotor test (by turning the motor shaft), and will measure EMI.
