Operating Precautions
WARNING
• Connect the test lead correctly.
• Wear gloves of rubber or similar material during
measurement.
• Ventilate the rooms where batteries have been
installed before measuring batteries to prevent
explosions. Sparks may occur when a test lead is
connected to a battery to be measured, which can
ignite any accumulated inammable gases such as
hydrogen.
CAUTION
• After measuring a high-voltage battery, rst short-circuit
the test lead to discharges the DC elimination capacitor
connected across the lead before continuing to measure
a low-voltage battery. Otherwise the low-voltage battery
may be subject to an excess voltage, causing damage
to the battery.
• To avoid damage to the instrument, do not apply voltage
to the EXT.HOLD and TEMP.SENSOR terminal.
