Fluke 1522 User Manual

The Hart 1522 is a low-cost, high-accuracy digital thermometer readout de-
signed to be used with PRTs and thermistors. The unique combination of fea-
tures makes this instrument suitable for a wide variety of applications in
industry. Features and capabilities of the 1522 include the following:

• Accepts input from platinum resistance thermometers (PRTs) and therm-

istors

• Works with Hart’s INFO-CON probe connector (which is partially based

on U.S. Patent 5,857,777) to automatically recognize the type of sensor
and its characteristics

• Alerts the operator automatically when the probe calibration or meter cal-

ibration expires

• Measures with an accuracy of ±0.025°C at 25°C with PRTs and ±0.005°C

at 25°C with thermistors

• Accepts three- or four-wire sensors to eliminate lead resistance errors
• Measures with a fast one-second measurement cycle
• Displays maximum, minimum, and delta temperatures
• Uses a unique factory-assigned passcode to protect programmed settings
• Displays measurements and settings on a high-contrast LCD display
• Communicates with other equipment or a computer using an RS-232 se-

rial interface

• Can be powered from its AC adapter or rechargeable battery
• Stores up to 10,000 readings with reading, units, date, time, and label in

autologging mode at user selected intervals

• Stores up to 100 readings with reading, units, date, time, and label in de-

mand logging mode

• Contains an infrared interface for fast downloading of logged data
• Stores 25 labels (8 characters) for easy recognition of logged data
• Stops logging once maximum readings are stored. Memory must be

cleared to store additional data

• Starts and stops logging both from the front panel and through the

RS-232 and infrared interfaces

• Allows user to select a label for every reading stored in demand logging

mode
