INSTALLING THE BATTERY:
The battery compartment is located on the underside of the case, at the bottom of the
handle.
1. Open the battery compartment by sliding the lid back while pressing on the release
indent.
2. Ensure correct polarity, and push the battery in flush with the bottom board until the
connectors snap together on both sides.
3. Replace the battery compartment lid.
LOW BATTERY
:
The meter features a battery status monitor, designed to warn the user as well as protect
measurement accuracy from impending battery failure conditions. The battery warning is
triggered by either continuous or temporary low voltage conditions. Visible (a battery
icon on the top right side of the display) and audible (buzzer warble) indicators
accompany a battery warning.
Once a permanent low battery condition is detected, all measurement functions are
disabled. Enough power remains for other menu functions, but almost any user action at
this time causes a low-battery warning to be generated. The battery should be replaced
immediately. If the battery reaches critical levels, the meter will refuse to stay on at
power-up.
This gradual warning system is intended to provide the user advanced battery status
notice and give ample time for replacement before operational limitations occur.
METER USE
TO POWER THE METER ON:
1.
Before turning on the meter, firmly insert the sensor into the top of the meter,
making sure to align the pin-out on the DIN connector.
2.
