3 General Operations

The AM1710 is equipped with a four-wire cable (see Figure 1).

Four lead wires are used to cancel lead wire resistance. For best

results, the readout device should be equipped to handle four-

terminal resistors. The lead wires can be distinguished by

insulation colors. Lead wire pairs attached to each end of the

sensor are identified by red/black and white/blue insulation.

AccuMac recommends 1mA as drive current to ensure the best

measurement.

To achieve the best accuracy, allow sufficient time for PRT to

stabilize before taking the readings.

Stem effect can cause measurement errors due to heat lost or

gained by the sensing element through the thermometer stem. To

minimize the error, appropriate immersion depths are required. A

practical way to determine the minimum immersion depths is to
