Ranger Simulators 1, 3 and 5 Operation 3
2.0 Ranger Simulators 1, 3 and 5 Operation
To get the most out of the simulator, remember the following:
• Dampness, water, or other contaminants on the face of the simulator can cause leakage current between
terminals. Keep the face and the terminals clean and dry when using the Ranger Series simulator.
• The binding posts are heavily plated, but should some corrosion occur, clean the posts before attempting to
use the unit.
• If the simulator has been at an unusual temperature environment for many hours (i.e., left in a truck during
winter or summer), allow several minutes for the unit to stabilize to the ambient temperature of the scale
before using.
• Excitation voltage should not exceed 15 volts DC or AC (RMS). Higher voltages will degrade the accuracy
and possibly damage your simulator.
• When using the Ranger 5 simulator for testing stability or drift, or when recalibrating an indicator, make sure
the vernier range select switch is in the Off position.
