C. TECHNICAL DATA

1. Features and Benefits

Agency Meets CE and IEC 1010.

Analog Bar Displays rapidly changing input

Graph signals.

NCV Non-contact voltage detection. Detect

the presence of voltage without con-

tacting the circuit.

P-H Captures min / max peak.

MAX/MIN Records Min/Max readings for all

functions and ranges.

REL Measurements made are displayed

relative to a stored value.

Auto Off Automatically powers off after 30

minutes of inactivity.
