Specifications of this calibrator are defined for 1 year period so it should be periodically tested (and
adjusted if necessary) within the same period of time. If you don’t have the necessary equipment or can’t
do the calibration on your own, please ask local Meatest representative to help you calibrate this device.
Following instruments are required for performance verification test:
-
8½ digit multimeter like Fluke 8508A/8588A or similar with uncertainty10 ppm or better on DC
voltage, 100 ppm on AC voltage
- Single Channel LF Power Meter / Power Analyzer 1000V/30A like Zimmer LMG6100, LMG500
or similar with uncertainty 0.025 % or better.
- Counter Keysight 53181A or similar with uncertainty 1 ppm or better.
- LCR meter type Keysight U4980A or similar with uncertainty 0.1 % at 1 kHz or better
-
Megaohmmeter Quadtech 1865 or similar with resistance range up to 100 GΩ or more (when HVR
option is installed)
- RF voltmeter/wattmeter type Thermal Power Sensor Rohde&Schwarz NRP-Z51 or equivalent with
50Ω characteristic impedance (when SCO option is installed)
1. Place the calibrator to the standard condition and let it switched on for at least one hour in a
laboratory in reference conditions 22 °C to 24 °C.
2. Set Terminal ground item in 9010+’s SOURCE SETUP menu to ON in order to suppress mains
noise during measurement.
3. Connect output/input terminals of the calibrator to the input voltage terminals of the standard
device. Set parameters which enables the most accurate measurement in standard device.
4. Use table in chapter 5.3 to verify all recommended test points. Measured deviation should not
exceed the limits in tables.
a. DC voltage test
b. AC Low frequency SINE voltage test
c. DC current test
d. AC current SINE test
e. AC power and phase test
f. Variable resistance LVR test
g. Fixed resistance LVR test
h. Variable capacitance test
i. Fixed capacitance test
j. High Voltage Resistance Variable (HVR option only)
k. High Voltage Resistance Fixed (HVR option only)
l. Frequency test (1 MHz)
m. HF voltage test (SCO option only)
n. Non-sinusoidal voltage test
o. Meter test covering DC voltage, DC current, frequency and resistance tests
