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.
