⑨Terminal Cover

Used  to  enclose  the  input  terminals  (COM  and  V/Ω )  when  the

OUTPUT terminal is in use, thus avoiding accidental application of

voltage to the instrument. 

⑩OUTPUT 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.

⑪COM Terminal

Accepts the black test lead for voltage or resistance measurement.

⑫V/Ω Terminal

Accepts the red test lead for voltage or resistance measurement.

⑬Safety Hand Strap

Prevents the instrument from slipping off the hand curing use.

⑭Test Leads (M-7017)

Connect  to  COM  and  V/Ω Terminal  terminals  for  resistance

measurement.

⑮Output Plug (M-8201)

Insert  this  plug  into  the  OUTPUT  terminal  to  obtain  DC  output

voltage.    Connect  suitable  connection  cord  to  the  plug  when  it  is

used.

⑯Barrier

It  is  a  part  providing  protection  against  electrical  shock  and

ensuring the minimum required air and creepage distances.

⑤AC/DC Button

Used  to  switch  the  instrument  between  the  AC  and  DC  modes.

The instrument is set to the AC mode when it is powered on.  Press

this button to select the DC mode.

⑥ Mode Button

A  press  of  this  button  on  a  current  or  voltage  range  turns  the

instrument  to  the  MAX  measurement  mode  with 

腋胙腴

shown  on

the display.  Press the button again to exit the MAX mode.

A press of the button on the resistance range turns the instrument

to  the  continuity  check  mode  with 

symbol  shown  on  the

display.  In this mode, the buzzer beeps when the reading is about

50Ω or  less.    Press  the  button  again  to  exit  the  continuity  check

mode.

⑦Zero ADJ./RESET Button

Used  for  zero  adjustment  on  400A  DC  range  or  for  resetting  the

reading in the MAX mode.  

胙腮腱腆

symbol is shown on the display

when  zero  adjustment  is  enabled  on  400A  DC  range.    (Zero

adjustment is available only on 400A DC range. )

⑧LCD Display

Field  effect  type  of  liquid  crystal  display  with  maximum  counts  of

3999 and  microprocessor-controlled annunciators and the decimal

point.
