Measurement Range
There are two resistance modes: resistance measurement mode and resistance measurement
mode at low voltage.
Measure and display two types of parameters: resistance parameters and temperature
parameters. Parameters of resistance range, current, resolution, etc. have been displayed in
diagram 3-1-2.
ST2515 has 11 DC resistance ranges: 20mΩ, 200mΩ, 2Ω, 20Ω, 200Ω, 2kΩ, 20kΩ, 100kΩ, 1MΩ,
10MΩ, 100MΩ.
ST2515 has 4 DC low voltage resistance ranges: 2Ω, 20Ω, 200Ω, 2KΩ.
The testing range of temperature of ST2515: -10°C to 99.9°C.
(OVC applicable in ranges up to 20kΩ; see also

Operation steps for setting measurement ranges:
1)
Touch the range zone, the following soft keys will be displayed.
AUTO Set the range mode as AUTO.
HOLD Switch the range mode from AUTO to HOLD. When the range mode is set as HOLD,
the range will be locked at the current measurement range which is displayed in the RANGE
