CAN/CSA-C22.2 No. 1010.1-92
Analog Low Isolation 20 V
EMC Designed to comply with FCC Rules Part 15; VFG 243/1991. If used in
areas with Electromagnetic fields of 1 to 3 V/m, resistance outputs have a
floor adder of 0.508 •. Performance not specified above 3 V/m. This
instrument may be susceptible to electro-static discharge (ESD) from direct
contact to the binding posts. Good static aware practices should be
followed when handling this and other pieces of electronic equipment.
Line Power [2] • Line Voltage (selectable): 100 V, 120 V, 220 V, 240 V
• Line Frequency: 47 Hz to 63 Hz
• Line Voltage Variation: ±10% about line voltage setting

Absolute Uncertainty Definition The 5500A specifications include stability, temperature coefficient, linearity,
line and load regulation, and the traceability of the external standards used
for calibration. You do not need to add anything to determine the total
specification of the 5520A for the temperature range indicated.

[1] After long periods of storage at high humidity, a drying out period (with the power on) of at least one week may be
required.
[2] For optimal performance at full dual outputs (e.g. 1000 V, 20A) choose a line voltage setting that is ± 7.5% from
nominal.
[3] The DC Current ranges 0 to 1.09999 A and 1.1 A to 2.99999 A are sensitive to storage temperatures above 50 °C.
If the 5520A is stored above 50 °C for greater than 30 minutes, these ranges must be re-calibrated. Otherwise, the
90 day and 1 year uncertainties of these ranges double.
