Warning. Read before use
To avoid possible electrical shock or personal injury, follow these instructions and guidelines.
▶ Make sure that the Meter should be used only as specied in this manual
▶ Stop using the Meter or test leads if they look damaged, or if the Meter is not operating
properly
▶ Make sure that only the rated voltage should be applied to the Meter, as marked on meter
▶ Replace the battery immediately as soon as the low battery indicator( ) is displayed
▶ Disconnect the test lead from test point before changing the meter function and range
▶ Do not measure voltage out of specication(over 1,000V)
▶ Verify the meter’s operation by measuring a known voltage
▶ Use caution with voltages above 20V ac rms, 42 V ac peak, or 60 V dc.
▶ Disconnect circuit power and discharge all high voltage capacitors before testing resistance,
continuity, diodes, or capacitance.
▶ Remove the test leads before opening the case or battery cover.
▶ The Meter is for indoor use only(IPX0)
▶ Use the Meter with test probe(Model # GTP01)provided by GSI.
▶ The protection provided by the Meter may be impaired if the Meter is used ina manner not
specied by the manufacturer.

Introduction
Overview
The Protek D705/D705T are true-RMS multimeters and battery-powered with a 5000-counts, 25
segments bar graph. These multimeters are fully compatible to CAT III and CAT IV IEC 61010
standards, which denes four overvoltage categories(CAT I to IV) based on the magnitude of danger
from transient impulses.
Measurement Category I:
This category is for measurements of voltages from specially protected secondary circuits. Such
voltage measurements include signal levels, special equipment, limited-energy parts of equipment,
circuits powered by regulated low-voltage sources, and electronics.
Measurement Category II:
This category refers to local-level electrical distribution, such as that provided by a standard wall
outlet or plug in loads (for example, 115 AC voltage for U.S. or 200 AC voltage for Europe). Examples
of Measurement Category II are measurements performed on household appliances, portable tools,
and similar modules.
Measurement Category III:
This category refers to measurements on hard-wired equipment in xed installations, distribution
boards, and circuit breakers. Other examples are wiring, including cables, bus bars, junction boxes,

switches, socket outlets in the xed installation, and stationary motors with permanent connections
to xed installations.
Measurement Category IV:
This category refers to origin of installation or utility level measurements on primary over-current
protection devices and on ripple control units.

Backlight Automatically turns off after 1 minutes to save battery life
MIN MAX AVG Minimum, maximum and average reading memory
Manual or auto ranging In auto range, the meter selects the range with the best resolu-
tion for the present measurement value
Auto Power Off The meter shuts off automatically after 30 minutes if it is not
used.
Data Hold HOLD. Press this button to turn hold mode ON and OFF. When
the hold mode is activated, the meter beeps, freezes the display,
and displays the HOLD indicator on the LCD. HOLD mode freezes
the display for later view.
Range Hold RANGE. Use the RANGE button to manually select a range. Press
and hold RANGE button for two seconds to return the meter to
auto range mode. The meter is in auto range mode when the
AUTO indicator is on.
