Use of the 6V9130 Temperature Adapter Group{0776} Caterpillar

Introduction

6V9130 Temperature Adapter Group (1) 6V9129 Temperature Adapter. (2) 6V9131 K-Type Thermocouple Probe.

The 6V9129 Temperature Adapter (1) converts the input from a K-type thermocouple to 1mV/°C or 1mV/°F output for use with a Caterpillar 6V3030, 6V7070 or 6V7800 Digital Multimeter.

By plugging the adapter [with the 6V9131 K-type Thermocouple Probe (2) attached] into the VOLT and COMMON inputs of a digital multimeter, the user will have the measured temperature displayed on the multimeter.

Temperature adapter (1) operates with a 9-Volt battery and includes both cold junction compensation and two point linearization to ensure accuracy over the full operating range of the instrument.

Do not perform any procedure, outlined in this publication, or order any parts until you read and understand the information contained within.

Safety Information

* Do not exceed a maximum of 500 Volts dc or rms at the thermocouple inputs.

Show/hide table

One input of the thermocouple connector is connected to the multimeter COMMON input. If the thermocouple used with the temperature adapter is to be used to measure the temperature of a device that has a voltage with respect to the ground, the multimeter COMMON input must not be connected to ground. To do so may apply a direct short to the voltage of the device under test.

Show/hide table

Always use care when taking measurements of hot and cold material.

6V9129 Temperature Adapter Operation

1. Battery Level Test - Before making temperature measurements, check the battery voltage level to be sure of proper operation of the unit.

* Connect 6V9129 Temperature Adapter (1) to multimeter (2) being used for temperature measurement. Adjust the multimeter to the 20 Vdc range.

* Put adapter ON/OFF/TEST switch to (3) to "TEST" position.

* If the reading displayed is less than 7.0 Vdc, install a new battery in adapter (1). See BATTERY REPLACEMENT FOR 6V9129 TEMPERATURE ADAPTER.

2. Adjust multimeter (2) to Vdc function as follows:

NOTE: The decimal point is not used when reading temperatures above 199.9°C or 199.9°F.

Example: A reading of 0.565 = 565°: 1.200 = 1200°.

NOTE: Due to temperature adapter internal limitations, the maximum temperature to be measured should not be more than 900°C (1652°F).

3. Plug the connector of the thermocouple probe or wire into the input connection of adapter (1). Do not force the connector into the adapter.

To ensure correct polarity for the thermocouple, the connector can only be installed one way. The narrow positive (+) terminal must plug into the left side (narrow slot) of the adapter input connector.

Use °C/°F Switch (4) to select the desired temperature reading.

4. Move ON/OFF/TEST Switch (3) to the ON position.

5. Put the thermocouple tip in contact with the area where temperature is to be measured. Allow a few seconds for the temperature reading on the multimeter to become stabilized.

6. Read the temperature displayed on the multimeter (2). When temperature measurement is complete, move ON/OFF/TEST Switch (3) to the OFF position to prolong battery life.

Battery Replacement for 6V9129 Temperature Adapter

1. Remove four screws (1). Separate the two halves of case (2), and remove battery (3).

2. Install a new heavy duty or alkaline 9 Volt battery.

3. Assemble the case; be sure that battery pad (4) and plugs (5) are in their correct position.

4. Install and tighten four screws (1).

NOTE: When connecting a thermocouple connector to the temperature adapter make sure the thermocouple connector is correctly plugged into the adapter. The narrow positive (+) blade of the thermocouple connector must plug into the narrow positive socket (7) of temperature adapter connector (8).

Troubleshooting

If the temperature reading becomes erratic or is questionable, make sure the multimeter is working correctly. Then, check the battery voltage of the 6V9129 Temperature Adapter. See 6V9129 TEMPERATURE ADAPTER OPERATION.

If the test indicates correct operation of both parts, do the procedure that follows:

1. Inspect the thermocouple to make sure the wire is correctly connected to yellow thermocouple connector (1).

2. Remove two screws (2), and lift off cover (3).

* Make sure the thermocouple wire with the red insulation jacket is connected to the negative (-) blade terminal. [The negative (-) blade terminal is wider than the positive (+) blade terminal.] The thermocouple wire with the yellow insulation jacket should be connected to the position (+) blade terminal.

NOTE: Be sure the two wires are not touching (shorted) to each other.

3. Repair the connections if necessary, then install cover (3) and screws (2).

* If additional test, calibration or performance check information is needed, order a Service Manual for a Beckman Model TC-253 Temperature/Voltage Converter. Order Beckman Instructions FG3000-940-133 from the address given at the back of this instruction.

8T0458 Thermocouple Wire and/or 6V9131 Thermocouple Probe Repair

With normal use, 8T0458 Thermocouple Wire (1) and 6V9131 Thermocouple Probe (2) should not need service or adjustment. The only repair that can be made to either part is the replacement of thermocouple connectors (3) or (4).
