Features

Feature Description

Digital Display 6000 counts, updates 4 x second

Analog Bargraph Display 33 segments, updates 40 x second

Backlight (177 & 179 only) Automatically turns off after 2 minutes to save battery life

The timeout feature can be disabled with a power-up option

HOLD & Auto HOLD HOLD: freezes the display at the push of a button

Auto HOLD: Display holds present reading until it detects new stable input,

then the meter beeps and displays new reading

MIN MAX AVG Minimum, maximum, and average reading memory

Manual or auto ranging In auto range, the meter selects the range with the best resolution for

the present measurement value

Fast continuity/open detection The beeper sounds with a stretched pulse for opens or shorts as

brief as 250 µs

Test lead alert The message “LEAd” appears briefly on the display when the rotary switch

is moved to or from any A (Amps) position

Power-up options (1) Turn on all LCD segments, (2) Disable beeper, (3) Disable sleep mode,

(4) Enable smoothing, (5) Disable backlight timeout (Models 177 & 179 only)

Closed-case calibration No internal adjustments needed

Probe holders The instrument comes with built-in probe holders for probe storage and

for convenience when making measurements

Battery access door Battery replacement without voiding calibration

High-impact overmold case Integrated overmolded protection provides superior impact protection for

your meter
