80T-150UA
Universal Temperature Probe
Instruction Sheet

Introduction
The Model 80T-150UA Universal Temperature Probe is a self-contained
temperature-to-voltage converter. The probe is designed to provide a
direct temperature reading when it is connected to any high impedance
DMM that is capable of 1 mV resolution and at least a 300-count full
scale readout capability. Output is 1 mV per degree (Celsius or
Fahrenheit). Two switch-selected temperature output scalings are
provided:

F1.eps Figure 1. Initial Case Temperature Above Ambient vs Meter Reading Above Ambient Operation Use the following procedure to operate the 80T-150UA probe: 1. Connect the banana plugs on the 80T-150UA to the input terminals of a high impedance DMM. Observe polarity. 2. Select a dc voltage range that will provide at least 1 mV resolution (1 mV/degree) and a full scale readout that will encompass the expected temperature. The 2 V range of a 3 1/2-digit DMM is adequate. Ignore readin

Battery Replacement XWWarning To avoid electrical shock, remove the probe from the measurement surface before opening the case. Totally reassemble the instrument before attempting to use it. 1. Set the power switch to the OFF position. 2. Disconnect the 80T-150UA from the DMM. 3. Turn the 80T-150UA so the power switch is facing down. Remove the single screw located between the banana plugs. 4. Grasp one case half in each hand. Pull the two halves apart, beginning at the end with the ba
