1.3 Measurement Category
Measurement Category
The instrument can operate under measurement category Ⅰ.
Warning:
This instrument can only be used for measurements within its specified
measurement categories.
Definitions of measurement categories
Measurement Class I refers to measurements made on circuits not directly
connected to the main power supply. For example, circuits that are not derived
from the main power supply, especially from the protected (internal) main power
supply. In the latter case, instantaneous stress changes. Therefore, the user
should be aware of the instantaneous capacity of the device.
Measurement Class II refers to measurements made on circuits directly
connected to low voltage equipment. For example, household appliances, portable
tools and similar equipment.
Measurement Class III refers to measurement in construction equipment. For
example, switchboards, circuit breakers, circuits (including cables, busbars,
junction boxes, switches, sockets) in fixed equipment, equipment for industrial use,
and other equipment (for example, fixed motors permanently connected to fixed
equipment).
Measurement class IV refers to measurement at the source of low-voltage
equipment. For example, electricity meters, measurements on primary overcurrent
protection equipment, and measurements on pulse control units.
1.4 Working Environment
Temperature
Operating: 0℃ - 50 ℃
Non-operating: -20℃ - 60 ℃
Humidity
≤+104℉(≤+40°C): ≤90%RH
106℉~122℉ (+41°C ~50°C): ≤60%RH

Warning:
To avoid short circuit or electric shock, do not operate the device in a damp
environment.
Altitude
Operating and Non-operating: 3,000m (10,000 feet).
Random vibration: 0.31g RMS from 50Hz to 500Hz, 10 minutes in each axial direction.
When not operating: 2.46g RMS from 5Hz to 500Hz, 10 minutes in each axial direction.
ESD Category
ESD + 8 kv
Installation (overvoltage) Category
This product is powered by a main power supply conforming to Installation (overvoltage)
category II.
Warning:
Ensure that no overvoltage (e.g., lightning) reaches the product. Otherwise, the
operator may be in danger of suffering from electric shock.
Definitions of Installation (overvoltage) category
Installation (overvoltage) category I refers to the signal level, which is applicable to the
device measurement terminals connected to the source circuit. Measures have been
taken to limit the instantaneous voltage to the corresponding low level.
Installation (overvoltage) Class II refers to the local distribution, which is applicable to
equipment connected to the AC line (AC power).
Degree of pollution
Class 2
Definition of pollution level
Pollution level 1: No pollution, or only dry non-conductive pollution. This pollution
level has no impact. For example, clean room or air-conditioned office
environment.
Pollution level 2: Generally, only dry non-conductive pollution occurs. Transient

conduction due to condensation may sometimes occur. For example, general
indoor environment.
Pollution level 3: Conductive pollution occurs, or dry non-conductive pollution
becomes conductive due to condensation. For example, an outdoor environment
with a canopy.
Pollution level 4: Permanent conductive pollution through conductive dust, rain,
or snow. For example, outdoor places.
Security level
Level 1 - Grounded products
1.5 Maintenance and Cleaning

4.4 Storage and replacement of batteries
4.4.1 Battery storage
Lithium-ion batteries can be stored in clean, dry and ventilated rooms. Avoid contact
with corrosive substances and keep away from fire and heat sources.
If the instrument is not used for a long time (such as more than 6 months), the battery
should be charged 50% to 70% and be removed from the instrument to store in a dry
and cool environment.
If the lithium battery appears broken, rust, leakage, swelling, etc., it needs to be taken
out immediately and scrapped.
