1. Product Introduction
HPM-300A is a consumption/standby power analyzer and a practical and economical handheld-type
wattmeter. It enables the measurement of the power consumption (including standby very low power) of
home appliances and business equipment with 0.5mW to 7.5 KW power consumption, in a Plug & Play
way {with clamp sensor, it can measure up to 220 KW power consumption}, thus offering simple and easy
operation even by users at production plants and industrial sites. It can also measure AC, DC, and
combined electric power consumption.

⊙ Safety Instructions
This equipment has been designed in accordance with the CE CAT II & FCC safety standards.
Users, however, must see to it that they have a thorough knowledge of the guidelines for the use of
the equipment, as shown below, and must use it with full attention, to ensure its safe operation.
- Do not load general batteries, only rechargeable batteries, and do not use an AC adaptor while
loading general batteries (the Li-ion batteries are built-in).

6. Range Setup
This instrument provides both auto and manual range measurement in current channel.
Refer to the following current range configuration table.
※ The default range after power on is auto range.
※ Manual range measurement is necessary when you need quick measurement response or pulse input.
