GENERAL INFORMATION
In 4-wire configurations, accuracy is unaffected by lead resistance and resistance differences
between leads.
NOTE:
These instruments measure input voltages on all 4 terminals, and are able
to distinguish between 2-4 and 3-wire hookups. Switching between these
measurement modes is automatic.
2. Set instrument to METER mode.
3. Use the Sensor-Select key to set the instrument to the appropriate function and range.
NOTE:
Due to limited display area, 100
Ω
and 1000
Ω
RTD's are indicated on
the display by a momentary readout of "RTD-100" (or "RTD-1000")
when first selected.
Thermistors are identified by a momentary alpha-numeric readout of "Y-
400" (signifying YSI Series-400 type thermistor).
Any of these readouts can be recalled by turning the unit off and back
on
.
