4 Quick Start
This section briefly explainsthe basics of setting up and operating your 1504
thermometerr eadout.

4.1 Unpacking

Unpack the thermometer carefully and inspectit for any damage that may have
occurred during shipment.If there is shipping damage, notify the carrier
immediately.
Verifythat the following components are present:
1504 Thermometer
Extra Probe Connector
Power Cord
Manual
Probe (optional—must be purchased separately)
Battery Pack (optional—must be purchased separately)

4.2 Power

Your1504 is configured for either 115 VAC(±10%) operation or 230 VAC
(±10%) operation.Be careful to only connect the 1504 to a mains supply of the
correct voltage.Otherwise, the instrument may be damaged. The required volt-
age isindicated on the back of the 1504. Power requirements are listed in Sec-
tion 3.1, Specifications.The IEC type power cord connects to the back of the
1504. The cordmust be plugged in to a grounded outlet. The power switch is
located atthe back of the 1504. The instrument can also be powered with a DC
battery option (see Section 4.4, DC Power Option).
When the 1504 is poweredon, wait briefly while it initializes. It will then begin
measuring and displayingtemperature.
Because of the quality of the components used in the 1504, it exhibits nearly
negligible drift as it warmsu p. The warm-up drift is typically less than 5 ppm.
Nevertheless,to ensure the best accuracy and stability, you may want to allow
the 1504 towarm up for ten minutes before use.
Accurate measurementrequires that the probe be connected properly to the in-
put and the correct probe characterization set.

4.3 Connecting the Probe

The thermistoror RTD probe connects to the back of the 1504 using a five-pin
DIN plug. Figure1 showshow 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 attaches
