Overview
The GS Yuasa GYT117 conductance tester provides a simple
method to screen the state-of-health for Valve Regulated Lead
Acid (VRLA) batteries ranging from 0.5Ah to 25Ah.
Specifications
Voltmeter operating range: +6.0 to +19.99 Vdc
Voltage accuracy: +/–50 mV across operating range
Operating temperature: –18 to 50°C (0 to 120°F)
Voltage test limits:
12V high = 13.80V
12V low = 12.00V
6V high = 6.90V
6V low = 6.00V
Siemens range: 20 to 1200S
CAUTION: Attempting to operate the GS Yuasa GYT117
beyond its specified operating range may result in permanent
damage to the tester.
Safety precautions
• Always comply with facility safety standards when performing
battery maintenance.
• Always use extreme caution when working with batteries.
• Safety glasses and other PPE should be worn. Failure to do so,
may result in personal injury.
• To avoid electrical shock, remove personal metal items such as
rings, bracelets, necklaces and watches.
• To determine if the battery can be safely tested, inspect the
battery for a bulging case, leakage, cracks in the case, or other
visible signs of defects or problems.
Conductance and Voltage measurements
Conductance is an indicator of a battery's state of health and its
ability to meet its rated capacity. The GS Yuasa GYT117 measures
and displays the direct current Voltage (Vdc) and conductance for
any 6 or 12 Volt battery rated between 0.5 and 25 Ampere hours
(Ah) of discharge capacity. DC Voltage is a measure of a battery's
electrical potential.
Conductance is a relative measure of a battery's ability to meet its
rated capacity. The GS Yuasa GYT117 displays the conductance
value in Siemens (S). In general, a high relative conductance
measurement is an indication of a good battery, and a low
measurement indicates a battery in degraded condition.
