WARNINGS
To ensure safe operation and service of the tester, follow these instructions.
Failure to observe these warnings can result in severe injury or death.
•
Before each use, verify meter operation by measuring
a known voltage or current.
•
Never use the meter on a circuit with voltages that exceed the
category based rating of this meter.
•
Do not use the meter during electrical storms, or in wet weather.
•
Do not use the meter or test leads if they appear to be damaged.
•
Ensure meter leads are fully seated, and keep fi ngers away from
the metal probe contacts when making measurements.
•
Do not open the meter to replace batteries while the probes
are connected to a voltage source.
•
Use caution when working with voltages above 60V DC,
or 25V AC RMS. Such voltages pose a shock hazard.
•
Always adhere to local and national safety codes. Use individual
protective equipment to prevent shock and arc blast injury where
hazardous live conductors are exposed.
FEATURE DETAILS
Indicators
Lights
•
LEDs light up numerical voltage level indicators,
as well as DC
+
, DC
, or both (AC) indicators.
•
Voltage detection will function without batteries installed.
Vibration
•
Instrument will vibrate in the presence of voltage
measurements that activate the 120V LED.
•
Vibration will function only with batteries installed.
Accuracy
Accuracy of indicator lights is 70% to 100% of the voltage displayed
to account for normal variations in supply voltage.
Voltage-type indicator LEDs (DC, AC) illuminate at around 12V.
Ghost Voltages
The approximate input resistance of 15k
Ω
will reduce the possibility of
false readings due to ghost voltages on de-energized lines.
Lead Spacing
Molded lead holders on the back of the ET50 are spaced correctly
to test tamper-resistant outlets.

This product has been tested to the requirements of
CAN/CSA-C22.2 No. 61010-1, second edition, including
Amendment 1, or a later version of the same standard
incorporating the same level of testing requirements
CAT III CAT IV
Designed for transient protection
on indoor measurements at
installations connected directly
to the primary source. Examples
include distribution panels and
lighting systems in large buildings.
Designed for transient protection
on outdoor measurements taken
at the primary supply voltage
source. Examples include outdoor
overhead or underground utility
service and electricity meter.
