• Pause Time Error
It means the difference between the operating time to a fixed pause time and the operating time to a pause time that varies.
The pause time characteristics are the main characteristics of CR timer (timer exploiting charge and discharge of capacitor C and
resistance R).
If the oscillation count timer (timer which comprises an oscillation circuit composed of CR and quartz and is operated by a counting
circuit inside IC or micro-computer which counts the reference signal) is used, the pause time error becomes almost negligible owing
to its principles of operation. Accordingly, the description about these characteristics may be omitted for the oscillation count timer.
• Equation for Each Error and Measurement Conditions
The operation time shall be measured, in principle, for retention time of 0.5 second and halt time of 1 second.
The measurement shall be repeated five times except for the initial test. The equation for each error and the measurement condi-
tions are shown in the table below:

• Functional Vibration Resistance
Means such a vibration as occurs in the
range where the contact closed with that
vibration during the use of the timer
remains closed for the specified time (3
or 1 msec.) minimum.
• Destructive Vibration Resistance
Means such a vibration as occurs in the
range where no part is damage with that
vibration during the transportation or use
of the timer and the operation character-
istics are maintained.
• Functional Shock Resistance
Means such a shock as occurs in the
range where the contact closed with that
shock during the use of the timer
remains closed for the specified time (1
ms) minimum.
• Destructive Shock Resistance
Means such a shock as occurs in the
range where no part is damaged with
that shock during the transportation or
use of the timer and the operation char-
acteristics are maintained.
• Mechanical life
Means the durability that is achieved
when the control output is performed in
the no-load state.

• Electrical life
Means the durability that is achieved
when the specified voltage and current
loads are individually applied to the con-
trol output while being turned ON and
OFF. Generally, the life of the timer is
represented by the number of times the
control output is performed. When a
load is connected to the control output,
the term of "electrical life" is used. When
no load is connected to the control out-
put, the term of "mechanical life" is used.
The electrical life is shorter than the
mechanical life, and becomes longer as
the load decreases. The life of the timer
is made longer by connecting a relay or
a similar part rather than directly switch-
ing a large load with the control output.
• Rated power consumption
Means the power that is consumed when
the rated operation voltage is applied to
the power circuit.
(Rated power consumption = rated volt-
age
• Rated control capacity
Means the reference value that is used
to determine the performance of the
switching part of the load. This value is
represented by the combination of volt-
age and current.

• Contact resistance
Means the combined resistance that
consists of the contact resistance
between contacts, and the conductor
resistance of pins and contact springs.
• Insulation resistance
Means the resistance between a contact
or a conductive pin like the pin to which
the operation voltage is applied, and a
dead pin or a non-conductive metallic
part like the time case, the base, or a
retaining screw; or the resistance
between contacts.
• Withstand voltage
Means the limit value that does not
cause breakdown when high voltage is
applied for one minute to the same loca-
tion as measured for insulation resis-
tance. The detectable leak current is
normally 10 mA. In special cases, how-
ever, it may be 1mA or 3 mA.
• Withstand surge voltage
Means the limit value that shows the
durability against momentary abnormal
voltage resulting from lightning or switch-
ing a conductive load. The surge wave-
form is represented by the standard
impulsive voltage waveform at ±(1.2 ×
50) µs or ±(1 × 40) µs.
