GS Yuasa GYT117 keypad and LEDs
1. UP ARROW - Press for 12 Volt batteries and to scroll to the
reference value (20 to 1,200 Siemens).
2. ENTER - Press to select the reference value, to start the test,
and to display conductance in Siemens (S).
3. DOWN ARROW - Press for 6 Volt batteries and to scroll to the
reference value (20 to 1,200 Siemens).
4. VOLTMETER - Press at any time to read DC Voltage.
The red LEDs above the keypad indicate the test mode and the
numerical value shown on the display (Voltage, Siemens, and
percent of reference). You can use the GS Yuasa GYT117 as a
Voltmeter at any point in the test procedure by pressing the VOLT
button.
Battery test procedure
1. Disconnect the battery from the system.
2. Connect the tester clamps to the battery terminals: red to
positive (+), black to negative (–).
3. Select the voltage by pressing the UP ARROW button for 12
volts or the DOWN ARROW button for 6 volts. Press ENTER.
4. Scroll to the reference value by pressing the UP ARROW or
DOWN ARROW buttons. Press ENTER. (The tester will default
to the last reference value entered).
5. Start the test by pressing ENTER. A series of dots will flash on
the display while the GS Yuasa GYT117 measures conductance
and Voltage, and calculates a percentage of reference.
6. The first value displayed is the percentage of reference.
7. To display the actual conductance value (S), press and hold the
ENTER button.
8. To display Voltage, press the VOLT button.

Troubleshooting
TOO LO: The battery's Voltage is below the specified operating
range (< 6.00V for a 6V battery or <12.00V for a 12V battery).
Note: If the battery is below 5.5V, the tester will not operate.
TOO HI: The battery's Voltage is above the specified operating
range (> 6.90V for a 6V battery or >13.80 V for a 12V battery).
999 (or 9999 when ENTER is pressed): The battery has exceeded
the range specified. Refer to 'Specifications' for the tester's
operating range.
Excessive electromagnetic interference may cause the tester to
reset. If the tester resets during testing, simply disconnect it from
the battery, reconnect and start the test process again.
Establishing a conductance reference value
Battery performance is temperature dependent. Allow the
batteries to reach room temperature before testing - ideally
around 25°C (77°F). Refer to the following battery temperature
compensation scales below for the compensation factor.
As conductance is a relative measure, you must first establish a
reference value by testing a sample number of new batteries.
To establish a reference value, record the average of at least ten
fully charged batteries of the same or similar models, preferably
within 90 days of their installation. GS Yuasa recommends that the
batteries should all test within 20% of each other (+/–10% of the
average). (Consult your battery supplier for conductance values).
If new batteries are not available, record the average of installed
batteries of the same or similar models regardless of age. If the
installed batteries test within 10% of each other, the highest value
can be used as a temporary reference until new batteries are
available for testing.
