Test Instruments

Maximum display range and accuracy for digital multimeters and digital clamp meters and environmental meters

Indicates the least significant digit.

It represents the error used for processing fractions when

converting from analog to digital.

MT-1860/1820: the maximum display range is "5999".

MT-1232: the maximum display range is "3999".

MT-1280/1270/1210: the maximum display range is "1999".

For example of measuring resistance at MT-1232

When ACV measument using the MT-1270, the maximum display

value is 199.9V, minimum display value is 0.01V.

Example

The accuracy of the AC200 V reading is ±(0.8%rdg+5dgt).

when measuring AC100V, the accuracy reading display range is 100.9~99.15.

100V±(0.8%+5dpt)

=100+(0.80+0.05) ~100-(0.80+0.05)

=100.9~99.15
