1. INTRODUCTION
Congratulations on your purchase of the Extech Model 382860 True RMS Power MultiMeter.
Four LCD displays offer four simultaneous readings e.g. during “POWER” measurements,
simultaneous displays of power, current, AC voltage and power factor can be viewed; AUTO
RANGE always selects the correct measuring range to achieve best accuracy; REL
(Relative) function allows the operator to measure a value with respect to a preset reference
value; CMP (Comparator) function allows a comparative measurement to be made (the
upper/lower limits can be defined); MEM (Memory) and RCL (Recall) functions permit 10
measurements to be stored in memory for later recall; AUTO-POWER-OFF extends the life of
the battery by turning off the meter if neither the rotary function switch nor any button is
operated for 12 minutes. The AC Adaptor required for Power measurements is included.
