– Compare the voltage displayed on the digital voltmeter with the pre-load
voltage given in the „Adjustment Specifications.“ If necessary, switch the
voltmeter to a lower measuring range (e.g., 200 mV DC).
– If the pre-load voltage measured exceeds the tolerance limits listed in the
specifications, you must adjust the preload.
– The data for preload test weights and preload voltage are listed in the
“Adjustment Specifications” below.
