SELECTING THE MEASUREMENT RANGE
The SEFELEC1500M has an automatic measurement range search mode.
This is the most practical operating mode for the user
. It is however possible in the case
where it is sought to increase the rapidity of the measurement to block the device in a range
(range change time: 150 msec. per range)
Press the active area of the "Range" parameters line:
Select the resistance range, the max. value indicated is equal to: Voltage / Imin and the min.
value is equal to Voltage / Imax.
With the following current ranges:

Below the min. value the display will indicate a
"UNDER RANGE"
message and - - - -
Beyond the max. value, the display will indicate a
"OVER RANGE"
message and will take
correct measurements up to 10 times the maximum value of the range.
