Indicating Element
Model: 758C
Application: General purpose indicating element when connected to a certified and compatible load receiving
element.
Identification: The self-destructive identification label for the Model 758C is located on the rear panel of the
enclosure.
Sealing: Provisions for lead-wire security seals to be applied to a metal tab beneath the end cap retaining
screws.
Test Conditions: The Model 758C was submitted for the purpose of this evaluation. The emphasis of the
evaluation was on device design, marking requirements, operation, and compliance with influence factor
requirements. The indicator was interfaced with a Cardinal Model 1250 LPAN (NTEP CC 89-030A2) weighing
element and a printer. The device was tested for discrimination, power interruption, zero tests, and print format.
Tests were also performed with line voltages of 100 VAC and 130 VAC and battery voltages of 5.8 VDC to 9
VDC. The indicator was interfaced with a load cell simulator and several increasing/return to zero tests were
performed. Accuracy tests were conducted over a temperature range of -10°C to 40°C (14°F to 104°F).
Type Evaluation Criteria Used: NIST Handbook 44, 2006 Edition; NCWM Publication 14, 2006 Edition
Evaluated By: M. Kelley (OH), S. Brenstuhl(OH), J. Morrison(OH)
Conclusion: The results of the evaluations and information provided by the manufacturer indicate the devices
comply with applicable requirements.
