4.2 Equipment Required for Verification
The primary source instrument used in the verification procedures of Fluke 434-II/435-
II/437-II is the Fluke 5700A. If not available, you can substitute another Calibrator as
long as it meets the minimum test requirements.
• Fluke 5700A Calibrator.
• Test Leads (4x), as supplied with the Calibrator.
• Extra set of test leads capable to withstand 1000 V rms.
Note: for good recognition it is recommended to use a black lead between the
Calibrator’s LO and the Analyzer’s Ground banana input.
• 50Ω Coax Cables (3 pieces required), Fluke PM9092 (0.5m, set of 3).
• Male BNC to Dual Female BNC adapter (3 pieces required), Fluke PM9093.
• Dual Banana Jack to female to male BNC (1 piece required), Fluke PM9082.
• 50Ω feed through termination (4 pieces required): Fluke PM9585.
• Battery Charger as supplied with the Analyzer.
4.3 Relation between Characteristics and Performance Test.
Test limits used are based upon the specifications in the Analyzer’s Users Manual. This
manual can be downloaded from www.fluke.com
.
Accuracy requirements are as follows:
• Accuracy of current channels (Arms AC+DC):
0.5% of measurement ± 5 counts.
Note: 5 counts equals 5 A @ Amps Scaling x1 AC+DC; 5 counts equals 0.5 A @
Amps Scaling x10 AC only.
• Accuracy of voltage channels Fluke 434-II (Vrms AC+DC):
0.5% of nominal voltage Vnom as adjusted under SETUP, Vnom (120 V, 230 V, or
400 V) @ input voltage range 1 ... 1000 Vrms.
• Accuracy of voltage channels Fluke 435-II/437-II (Vrms AC+DC):
0.1% of nominal voltage Vnom as adjusted under SETUP, Vnom (120 V, 230 V, or
400 V) @ input voltage range 1 ... 600 Vrms.
Input voltage range 600 ... 1000 Vrms: accuracy 0.1% of reading.
• Accuracy of voltage channels 6 kV (Transient capture rms reading):
2.5% of nominal voltage Vnom (e.g. 400 V).
• Bandwidth of current channels (Arms, Absolute):
5% of measurement ± 5 counts.
Note: Bandwidth measurement is based on the accuracy of the harmonics mode. The
Analyzer can measure harmonics up to the 50th. A nominal fundamental frequency
of 60 Hz requires a bandwidth of 50 x 60 = 3000 Hz.
Note: 5 counts equals 5 A @ Amps Scaling x1 AC+DC; 5 counts equals 0.5 A @
Amps Scaling x10 AC only.
• Bandwidth of voltage channels (Vrms, Absolute):
434-II/435-II/437-II: 5% of measurement (if applied voltage is ≥ 1 % of nominal
voltage).
Note: Bandwidth measurement is based on the accuracy of the harmonics mode. The
Analyzer can measure harmonics up to the 50th. A nominal fundamental frequency
of 60 Hz requires a bandwidth of 50 x 60 = 3000 Hz.
• Channel Isolation (Cross talk, Voltage to current input, x1, AC+DC):
Cross Talk from voltage into current channels: - 95 dB (= 56,234 times).
