Form 3S - Probewell MT-1/WT3 User Manual

Probewell Lab Inc.

Form 3S

Form 3S single-phase, 120 volts two-wire with CT is also compatible.
Caution: Never open a circuit-closing device if current is flowing in the CT primary.
Serious personal injury may result.
Note: Some older-design 3S, 240 V forms have higher impedance and will not reach
full HL when tested with MT-1/WT3. However, the socket will test as high as it can.
