Maximum display range and accuracy for digital multimeters and digital clamp meters and environmental meters
rdg(reading) Maximum display range Accuracy
The value on the digital display,readout. MT-1860/1820: the maximum display range is "5999". When ACV measument using the MT-1270, the maximum display
MT-1232: the maximum display range is "3999". value is 199.9V, minimum display value is 0.01V.
MT-1280/1270/1210: the maximum display range is "1999".
For example of measuring resistance at MT-1232

Example
dgt(dilgit) 4000k 4.000M The range is automatically switched so that the The accuracy of the AC200 V reading is ±(0.8%rdg+5dgt).
Indicates the least significant digit. 4000 4.000k display unit is M or k when measuring AC100V, the accuracy reading display range is 100.9~99.15.
It represents the error used for processing fractions when 100V±(0.8%+5dpt)
converting from analog to digital. 40 40.00 The reading is display with three digits. =100+(0.80+0.05) ~100-(0.80+0.05)
=100.9~99.15
