Страница: 225 / 255

8.1 Introduction
8-2 ZM2371/ZM2372
8.1 Introduction
The following maintenance is essential for using the device under the best condition.

Operation inspection: Check if the device operates properly.

Performance testing: Check if the device respects the rated values.

Adjustment, calibration: If the rated values are not satisfying, NF Corporation will make
the necessary adjustment or calibration to restore performance.

Damage repairs: When performance cannot be restored by the adjustment or
calibration, NF Corporation will identify the cause and location
of the damage and will execute repairs.
This instruction manual describes how to easily proceed with a performance testing.
For more accurate inspections, adjustments, calibration or repairs, contact NF Corporation
or one of our representatives.
The following measurement instrument and standard are needed for the performance test:

Frequency counter: Accuracy: within
±
10 × 10 -6

AC voltmeter: RMS value display, accuracy: within ±0.5% (120Hz, 1kHz), within
±1%(100kHz)

DC voltmeter: Accuracy: ±(0.5% + 0.3mV) (10V range)

Multimeter: Should be able to make a diode test for measuring the voltage at
1mA in test current

Standard capacitor: 10pF, 100pF, 1nF, 10nF, 100nF, 1μF (whose capacitance and
dissipation factor should be calibrated at 120Hz, 1kHz, 10kHz,
100kHz)

Standard resistor: 10mΩ, 100mΩ, 1Ω, 10Ω, 100Ω, 1kΩ, 10kΩ, 100kΩ, 1MΩ, 10MΩ
(whose DC resistance value should be calibrated, For the Standard
resistor to be used for accuracy test of AC impedance, its impedance
should be calibrated at 120Hz, 1kHz, 10kHz and 100kHz.)
8.2 Daily Maintenance
Install
ZM2371 / ZM2372
in a location that fills the installation requirements.
Installation conditions

“2.2.2 Installation Conditions”
When the case/panel surface needs cleaning, wipe with a soft cloth. To remove persistent
contamination, wipe with a soft cloth soaked with neutral detergent and wrung out.
Do not use any organic solvents like thinner or benzene, or any chemical cleaning cloth, as
they may cause the surface finish to deteriorate, tarnish, or come off.
8.3 Storage, Repacking, and Transportation
Store
ZM2371 / ZM2372
in a location that fills the installation requirements.
Installation conditions

“2.2.2 Installation Conditions”
When repacking is necessary, for transportation for example, use a case that is of sufficient
size and strength, use filling that can withstand the weight of the device and make sure the
device is sufficiently protected.
During transportation, handle the device, taking care not to apply strong shocks to the
device.
