the buzzer beeps when the reading is about 50Ω or less. Press the button
again to exit the continuity check mode.

Button : Used for zero adjustment on 400A DC range or for reset-
ting the reading in the MAX mode. "
" symbol is shown on the display
when zero adjustment is enabled on 400A DC range. (Zero adjustment is
available only 400A DC range.)
(8) LCD Display : Field effect type of liquid crystal display with maximum
counts of 3999 and microprocessor-controlled annunciators and the deci-
mal point.
(9) Terminal Cover : Used to enclose the input terminals (Lo and Hi) when the
OUTPUT terminal is in use, thus avoiding accidental application of voltage
to the instrument.
(10) OUTPUT terminal (for current measurement only) : Provides DC voltage in
proportion to the reading on an AC or DC current range. The voltage is
used for such purposes as long term monitoring with a recorder or other
recording devices. This terminal cannot be accessed on a voltage or
resistance range.
(11) Lo Terminal : Accepts the black test lead for voltage or resistance meas-
urement.
(12) Hi Terminal : Accepts the red test lead for voltage or resistance meas-
urement.
(13) Safety Hand Strap : Prevents the instrument from slipping off the hand
during use.
(14) Test Leads (Model 98072) : Connect to Lo and Hi terminals for voltage or
resistance measurement.
(15) Output Plug (Model 98012) : Insert this plug into the OUTPUT terminal to
obtain DC output voltage. Connect suitable connection cord to the plug
when it is used. (See section 3.3 OUTPUT Terminal)
(16) Barrier: It is a part providing protection against electrical shock and
ensuring the minimum required air and creepage distances.
