Page 15: Safety Information
Safety Information Safety Information This instrument is designed to comply with IEC 61010 Safety Stan- dards, and has been thoroughly tested for safety prior to ship- ment. However, mishandling during use could result in injury or death, as well as damage to the instrument. Using the instrument in a way not described in this manual may negate the provided safety features.
Page 16 Safety Information The following symbols in this manual indicate the relative importance of cautions and warnings. Indicates that incorrect operation presents an extreme hazard that could result in serious injury or death to the user. Indicates that incorrect operation presents a significant hazard that could result in serious injury or death to the user.
Page 17 Safety Information Accuracy We define measurement tolerances in terms of f.s. (full scale), rdg. (reading) and dgt. (digit) values, with the following meanings: f.s. (maximum display value or scale length) The maximum displayable value or scale length. In this instrument, the maximum displayable value is the range (V/div) times the number of divi- sions (10) on the vertical axis.

Page 20 Operating Precautions • The operating temperature range of the instrument is -10°C to 50°C. Do not use the instrument in an environment that is out of this range. • To avoid damage to the instrument, protect it from physical shock when transporting and handling.
Page 21 Operating Precautions • Use only the specified connection cables. Using a non-specified cable may result in incorrect measurements due to poor connection or other reasons. • Before using a clamp sensor or logic probe, read the instruction man- ual supplied with it.

Page 22 Operating Precautions About alkaline dry cell batteries • Do not mix old and new batteries, or different types of batteries. Also, be careful to observe battery polarity during installation. Otherwise, poor performance or damage from battery leakage could result. • Do not use LR6 alkaline batteries together with commercially avail- able nickel hydride batteries or other types of batteries.
Page 23 Operating Precautions • The battery pack is a consumable. If the battery capacity remains very low after correct recharging, the useful battery life is at an end. • When a battery pack that has not been used for a long time is used, charging may end before the battery pack is fully charged.
Page 24 Operating Precautions Using the AC Adapter • Use only the supplied Model Z1002 AC Adapter. AC adapter input voltage range is 100 to 240 V AC (with ±10% stability) at 50/ 60 Hz. To avoid electrical hazards and damage to the instrument, do not apply voltage outside of this range.
Page 25 Operating Precautions Connecting to the Terminals Connecting to the Analog Input Terminals • Note the following maximum input voltage and maximum rated voltage to earth. 600 V AC/DC (CAT III, II), 300 V AC/DC (CAT IV) If their voltages are exceeded, this device will be damaged and personal injury will result.
Page 26 Operating Precautions Connect the clamp-on sensors or connection cords to the instru- ment first, and then to the active lines to be measured. Observe the following to avoid electric shock and short circuits. • To avoid short circuits and potentially life-threatening hazards, never attach the clamp to a circuit that operates at more than the maximum rated voltage to earth, or over bare conductors.
Page 27 Operating Precautions Connecting to the logic terminals To avoid electric shock and short circuit accidents or damage to the instrument, pay attention to the following: • Maximum logic probe input voltages are as follows. Do not measure if the maximum voltage would be exceeded, as damage the instrument or personal injury may result.
Page 28 Operating Precautions When connecting to external control terminals To avoid electric shock or damage to the equipment, always observe the following precautions when connecting to external control terminals. • Always turn off the power to the instrument and to any devices to be connected before making connections.
Page 29 Operating Precautions About the Printer • The printer head and metal parts nearby become very hot. Be careful not to touch them because doing so may result in a burn. • Be careful not to cut a finger with the paper cutter. •...
