1. Disconnect the negative (-) battery cable.
2. The 2

gauge with mounting brackets supplied.
3. Connect one light wire to dash lighting circuit or to any 12 volt
source. Connect second light wire to ground.
4. Determine temperature module mounting location, preferably on
inside of firewall passenger compartment) protected from dirt and
liquids. Check that the meter harness and thermocouple
(temperature probe) wires reach the module. If mounting with
screws, drill holes for screws provided.
5. Pass thermocouple wires through existing hole in firewall or drill
9
⁄32” dia. hole and use provided grommet to protect wires.
6. Locate good chassis ground near temperature module. Using 18
gauge wire (preferably black) with lug terminal, secure it to ground.
7. Connect all wires to terminal block on temperature module and
locate a 1 Amp fused terminal on fuse panel to supply 12V power
to module.
8. Using pre-drilled holes, mount module to pre-selected location.
9. Use wire ties to hold wires together in vehicle.
10.Reconnect negative (-) battery cable.
1. To insure proper operation of the pyrometer, make sure the
terminal strip is free from contaminant and is securely fastened.
2. It is best to connect the pyrometer directly to the battery protected
by a 1 Amp fuse and switch.
Operation
Both channels are continuously monitored for peaks and alarm conditions, regardless of channel being displayed. Peaks and alarms are then
saved in memory so they can be viewed even after the unit is powered OFF and back ON.
WARNING
Use ONLY Quick-Lite models no. 5330, black and 5331, silver.
Pro-Lites exceed the current rating of the 2 channel pyrometer
and can not be used. Improper hook-up can cause permanent
damage to the pyrometer, thus voiding the warranty.

This document describes the installation and operation of the Auto Meter 2 Channel Pyrometer, designed for measuring Exhaust Gas Temperatures (EGTs) or Cylinder Head Temperatures. It covers models 4366, 4368, 4466, 4468, 5466, 5468, and 5766.

Function Description

The 2 Channel Pyrometer is an electronic device that continuously monitors and displays temperature readings from two independent channels. It is capable of tracking peak temperatures and alarm conditions for both channels, even when the unit is powered off and back on. The device is designed for use in automotive applications, likely for performance monitoring.

Important Technical Specifications

• Channels: 2 independent channels for temperature monitoring.
• Temperature Probes: Uses thermocouples for temperature sensing. The manual specifies yellow and red wires for Channel #1, and yellow and red wires for Channel #2, indicating Type K thermocouples are likely used.
• Gauge Sizes: Available in 2 5/8" and 2 1/16" diameter gauges for in-dash mounting.
• Power Requirement: Operates on 12V power, requiring a 1 Amp fused connection.
• Module Mounting: The temperature module should be mounted in a protected location, preferably inside the firewall of the passenger compartment, away from dirt and liquids.
• Quick-Lite Hook-up: Supports optional Quick-Lite models 5330 (black) and 5331 (silver) for lighting. Important Warning: Pro-Lites are explicitly stated to exceed the current rating and should not be used, as improper hook-up can cause permanent damage and void the warranty.
• ID Matching: For accurate readings, the ID numbers on both the pyrometer gauge and the temperature module must match.

Usage Features

The pyrometer offers several user-configurable features accessible through its display and buttons:

Display Modes

The pyrometer has two main display modes:

• Manual Mode: In this mode, the light above the "Auto/Man." button is OFF. Users can manually select which channel's temperature is displayed using the "Channel Select/Peak Recall" button.
• Automatic Mode: In this mode, the light above the "Auto/Man." button is ON. The meter automatically displays the higher temperature reading between the two channels. Manual channel selection is not possible in this mode.

The "Auto Mode" / "Man. Mode" button toggles between these two modes.

Channel Select

To select a specific channel for display (only available in Manual Mode), press the "Channel Select/Peak Recall" button.

Peaks

• Continuous Monitoring: Both channels continuously monitor and store peak temperature values, regardless of which channel is currently displayed. These peak values are retained in memory even after the unit is powered off.
• Displaying Peaks: To view the peak value for a desired channel, press and hold the "Channel Select" button until the "Peak" light turns ON.
• Clearing Peaks: To erase a stored peak value, press the "Peak Clear" button.
• Exiting Peak Display: To maintain the displayed peak value and return to normal pyrometer operation, press either "Channel Select" button.

Alarms

• Continuous Monitoring: Alarm conditions are continuously monitored for both channels, with red lights indicating an active alarm. Alarm settings are initially set to full scale by Auto Meter.
• Setting Alarms:
  1. Select the desired channel using the "Channel Select" button.
  2. Press the "Alarm Set/Store" button. The "Alarm" light above this button will flash.
  3. Use the "+" and "-" buttons to adjust the pyrometer's pointer to the desired alarm setting.
  4. Press the "Set/Store" button again to save the setting and exit the alarm set mode.
• Power Down Retention: Alarm settings are saved even after power down.

Maintenance Features

The manual provides several tips to ensure proper operation and longevity of the pyrometer:

• Terminal Strip Integrity: Ensure the terminal strip is free from contaminants and securely fastened for proper pyrometer operation.
• Direct Battery Connection: It is recommended to connect the pyrometer directly to the battery, protected by a 1 Amp fuse and a switch. This helps ensure a stable power supply.
• Wire Protection: When passing thermocouple wires through the firewall, use the provided grommet or an existing hole to protect the wires from damage.
• Secure Wiring: Use wire ties to keep all wires organized and secure within the vehicle.
• Grounding: Ensure a good chassis ground connection near the temperature module, using an 18 gauge wire (preferably black) with a lug terminal.

Warranty and Service

• Limited Warranty: Auto Meter Products, Inc. provides a 12-month limited warranty from the date of original purchase, covering defects in material and workmanship. The warranty is limited to repair or replacement of parts and does not exceed the original purchase price.
• Warranty Exclusions: The warranty is voided by breaking the instrument seal, improper use or installation, accident, water damage, abuse, unauthorized repairs, or alterations.
• Service Procedure: For service, products should be sent to Auto Meter in a well-packed shipping carton, including a note explaining the problem, phone number, and desired return timeframe.
