Accuracy
Rated accuracy: ±0.1% of capacity. Typical accuracy ±(0.1%+1d) of
reading. ‘d’ equals one displayable increment.
Resolution
Standard displayed resolution: 2000-2500 ‘d’ . Hi-Res mode increases
resolution to 5000-6250 ‘d’. Internal A/D resolution: 24 bits.

WARNING
The MSI-7300 has a safe mechanical overload of 200% of capacity.
Overloads greater than 200% may result in physical damage to the
link. The ultimate overload is rated to 500%-700% of capacity (see
Table 1-2). At ultimate overload, structural failure and dropped
loads may occur. Dropped loads may cause serious personal injury
or death.
Safe link mechanical overload, 200% of capacity. Ultimate link overload,
>500% of capacity. Typical ultimate overload is 700% or greater. Note that
the Dyna-Link is designed to have a greater safety factor than the connecting
shackles which have a typical ultimate safety factor of 600%
Battery operated, see Table 1-2 for battery size and quantity per unit.
Alkaline cells can be replaced with rechargeable NiMH cells.
Five digit, 1.22 in (31 mm) numeric digits.
Six digit, 1 in (26 mm) on 100000 lb units and higher
- 40°F to +122°F (-40°C to +50°C), Rated accuracy range -10°C to +40°C.

Programmable multifunction buttons for use as TEST, TOTAL, UNIT, PEAK,
TARE, NET/GROSS, VIEW TOTAL, PRINT AND High Res mode.
Fully digital calibration from the front panel or through a computer interface.
Standard, can be disabled internally.
Prolongs battery life by turning the power off after 15, 30, 45, or 60 minutes
(operator determined) of no Dyna-Link activity.
kg, lb, Tons (US short ton), Metric Tons, kilonewtons (other Units available
with custom calibrations).
Selectable - OFF, Low (LO), Medium (HI-1), High (HI-2).
Standard - Press button or automatic; TOTAL weight up to 99999 X1000
units
Uses unfiltered faster reading of A/D, (>220 readings per second).
Two internal standard setpoints and two ultrabright LEDs on indicator panel
Two independent 16 bit registers; register 1 updated each time the force
exceeds 25% of capacity; register 2 updated each time the force exceeds
overload; when register 1 exceeds 16383 or register 2 exceeds 1023,
display reads “LCnt” for load cell counter; test function shows the two
readings in order.
