100 to 600VAC Resolution & accuracy do not apply since the meter does not

display the voltage in this mode. The lamp at the top of the

meter’s display flashes when voltage is sensed and an audible

warning will sound

NOTES:

Accuracy specifications consist of two elements:

 (% reading) – This is the accuracy of the measurement circuit.

 (+ digits) – This is the accuracy of the analog to digital converter.

Accuracy is stated at 18

C to 28

C (65

F to 83

F) and less than 75% RH.
