Quick Start

4.1

Unpacking

Unpack the thermometer carefully and inspect it for any damage that may

have occurred during shipment. If there is shipping damage, notify the carrier

immediately.

Verify that the following components are present:

•

1502A Thermometer

•

Extra Probe Connector

•

Power Cord

•

Manual

•

Probe (optional—must be purchased separately)

•

Battery Pack (optional—must be purchased separately)

4.2

Power

Your 1502Ais configured for either 115 VAC (±10%) operation or 230 VAC

(±10%) operation. Be careful to only connect the 1502A to a mains supply of

the correct voltage. Otherwise, the instrument may be damaged. The required

voltage is indicated on the back of the 1502A. The 1502A may draw up to 10

VA. The IEC type power cord connects to the back of the 1502A. The cord

must be plugged in to a grounded outlet. The power switch is located at the

back of the 1502A.

When the 1502A is powered on, wait briefly while it initializes. It will then begin

measuring and displaying temperature.

Because of the quality of the components used in the 1502A, it exhibits nearly

negligible drift as it warms up. The warm-up drift is typically less than 5 ppm.

Nevertheless, to ensure the best accuracy and stability, you may want to allow

the 1502A to warm up for ten minutes before use.

Accurate measurement requires that the probe be connected properly to the

input and the correct probe characterization set.

4.3

Connecting the Probe

The RTD or SPRT probe connects to the back of the 1502A using a five-pin

DIN plug. Figure 1 shows how a four-wire probe is wired to the five-pin DIN

connector. One pair of wires attaches to pins 1 and 2 and the other pair atta-

ches to pins 4 and 5. (Pins 1 and 5 source current and pins 2 and 4 sense the

potential.) If a shield wire is present it should be connected to pin 3.

A two-wire probe can also be used with the 1502A. It is connected by attach-

ing one wire to both pins 1 and 2 of the plug and the other wire to both pins 4

and 5. If a shield wire is present it should be connected to pin 3. Accuracy may

be significantly degraded using a two-wire connection because of lead resis-

tance.
