6. Crest factor
Refer to the crest factor of voltage.
3.4 Measuring Resistance
Model ST1952 resistance measurement ranges are: 100Ω, 1kΩ, 10kΩ, 100kΩ, 1MΩ, 10MΩ, 100MΩ;
Maximum resolution: 1mΩ (on 100Ω range)
1. Select the desired measurement function.
DCR select
2. Connection manner
Connect test leads to the sources as shown in Figure 3-1 voltage measurement connections.
3. Range selection
Press
toggles auto ranging. Notice the
AUTO
annunciator is displayed with auto ranging. If
you want manual ranging, use the RANGE
and
keys to select a measurement range
consistent with expected resistance.
4. How to acquire more accurate measurement results
If the “
OVL.D
” message is displayed, press up
key to select a higher range until a normal
reading is displayed (or press
key for auto ranging). Use the lowest possible range for the best
resolution.
