Question 1

What is the SATA ST91521SC Dial Caliper and what can it measure?

Accepted Answer

The SATA ST91521SC is a stainless steel digital caliper designed for precise measurements. It can measure external dimensions with the outside jaws, internal dimensions with the inside jaws, and depth using the depth rod. It provides metric and imperial readings on a high‑resolution LCD, supports zeroing at any position, and includes a locking screw and an outer ring locking device to secure measurements.

Question 2

What are the main features and specifications of this caliper?

Accepted Answer

Key features include a stainless steel construction for durability, a high‑resolution LCD display, multiple measurement modes (internal, external, depth), metric and imperial unit support, zero setting, automatic shut‑off to save battery life, a locking screw to secure readings, and a portable design ideal for workshops and fieldwork.

Question 3

How do I switch between metric and imperial units on the caliper?

Accepted Answer

Use the unit button on the caliper to toggle between millimeters and inches. The display will cycle through the available units; you can set it to your preferred unit before taking measurements.

Question 4

How do I zero the display for relative measurements?

Accepted Answer

Close the jaws to the starting position, then press the Zero button to set the display to zero. This allows you to take relative measurements or compare measurements from a chosen reference point.

Question 5

How do I measure external dimensions, internal dimensions, and depth with this caliper?

Accepted Answer

For external dimensions, use the outside jaws to measure the external span across the object. For internal dimensions, use the inside jaws to measure the bore or hole diameter. For depth, extend the depth rod at the end of the caliper to the required depth and read the measurement on the display.

Question 6

What’s the purpose of the locking screw and outer ring locking device?

Accepted Answer

The locking screw secures measurements during transfer or when you need to lock a reading for later reference. The outer ring locking device helps stabilize the caliper’s position, reducing the risk of movement during measurement for improved accuracy.

Question 7

What are common use cases for this caliper?

Accepted Answer

It's well suited for woodworking, metalworking, automotive and mechanical tasks, or any precision measuring task where you need quick, accurate external, internal, and depth measurements with a durable stainless steel tool.

Question 8

How should I care for and store this caliper to maintain accuracy?

Accepted Answer

Wipe the caliper with a soft, dry cloth after use to remove dust and fingerprints. Avoid exposure to moisture, corrosive chemicals, and extremes of temperature. Store in its protective case when not in use. Regular calibration checks against a standard gauge can help maintain accuracy.

Question 9

How can I ensure the caliper remains accurate over time?

Accepted Answer

Periodically verify zeroing at multiple jaw positions, check measurements against a known reference (gauge blocks or calibration standards), and recalibrate if you notice drift. Handle the tool gently to avoid jaw misalignment or mechanical wear.

Question 10

How does this SATA caliper compare to other digital calipers on Fepy in terms of value?
