Fluke 712C [25/42] Measure temperature

RTD Calibrator

Measure Temperature

Use Resistance-Temperature Detectors (RTDs)

The Product accepts RTD types shown in Table 6.

RTDs are characterized by their resistance at 0 °C (32 °F),

which is called the “ice point” or R

The most common R

is 100 Ω. The Product accepts RTD

measurement inputs in 2-, 3-, or 4-wire connections, with

the 3-wire connection the most common. A 4-wire

configuration provides the highest measurement precision,

and 2-wire provides the lowest measurement precision.

To measure temperature using an RTD input, proceed as

follows:

1. If necessary, push  for Measure mode.

2. Push .

3. Use  or  to select the desired type, and push 

to confirm.

4. Push

 to select a 2-, 3-, or 4- wire connection.

5. Attach the RTD to input terminals as shown in

Figure 8.

Set Temperature Unit

The Product allows you to select the temperature unit °C

or °F.

Push  to switch to shift mode, and push  to set the

temperature unit to °C or °F.

The default temperature unit is °C.
