1-11 Performance Verification Models 2510 and 2510-AT
Sensor measurement accuracy
Use the following steps to verify that Model 2510 temperature sensor measurement accu-
racy is within specified limits. This procedure involves connecting characterized resistors to
the INPUT terminals and verifying sensor resistance readings are within required limits.
NOTE The following procedure tests thermistor sensor accuracy and will verify sensor
measurement accuracy for all sensor types.
1. With the power off, connect the 100
Ω
characterized resistor to the Model 2510 INPUT
terminals, as shown in Figure 1-4.
2. Turn on the Model 2510, and allow it to warm up for one hour before testing.
3. Select the Model 2510 voltage function by pressing the V key.
