(1) Conditions of guaranteed accuracy
(2) Additional accuracy (Add the following error components to the
instrument’s measurement accuracy.)
(3) Internal offset resistance
Measurement Specifications
Warm-up time Same as instrument with the Z3003.
Temperature and hu-
midity range for guaran-
teed accuracy 23±5°C, 80%RH or less
Period of guaranteed
accuracy 1 year
Accuracy specifica-
tions conditions When using a 2-wire setup, accuracy is guaranteed only after zero-adjustment.
Temperature coefficient From 0°C to 18°C and 28°C to 40°C, add a temperature coefficient of ±(1/10
of additional accuracy)/°C.
Effects of leak current Add a reading error as follows depending on the measurement current
(when using guarding)
(With humidity of less than 70% RH. If the humidity is greater than or equal to
70% RH, add the following rdg. error × 5.):
Effect of measurement
speed Add the f.s. error component as follows when the integration time is not a
whole-number multiple of the power supply cycle:
Effect of offset voltage Add the following resistance to the error when OVC is OFF
Effect of offset
resistance fluctuations When using a 2-wire setup, add the following wiring resistance to the error
component.
