A. Test Jacks:
The shielded black test lead’s male
SMA connector connects into the meter's female SMA
connector, and the red test lead’s banana plug connects
into the meter's banana jack.
B. Exponent LEDs:
These LEDs indicate the surface
resistance exponent value. They are color coded for
resistance decade quick checks.

ohms or 100,000,000 ohms).
C. OLED Display:
Displays the temperature, relative
humidity, battery life, test voltage and resistance
measurement.
D. Power Switch:
Slide the switch to the left to power
the meter OFF. Slide the switch to the right to power the
meter ON.
E. Black Pushbuttons:
Each black pushbutton
corresponds to the prompts on the bottom-left and
bottom-right of the display. These buttons are used to
access the Settings and Memory Recall menus and
scroll up and down between menu options.
F. Red Pushbutton:
Corresponds to the prompts
located in the bottom-center of the display. This button
is used to perform tests and select menu options. Press
and hold this button when in the Settings and Memory
Recall menus to exit and return to the home screen.
G. Battery Compartment:

M. Firmware Revision:
Displays the meter's firmware
revision.
N. Temperature:
Sets the unit of measurement for
temperature to either Fahrenheit (ºF) or Celsius (ºC).
O. Stabilization Mode:
Sets the meter's electrification
period setting to either Auto and Fixed Stabilization.
Auto - Enables a 15-second electrification period when
the measured resistance is 1 x 10
10
ohms or greater to
maintain test accuracy.
Fixed - Complies with ANSI/ESD S4.1 and enables a
15-second electrification period when the measured
resistance is 1 x 10
6
ohms or greater.
P. Beep:
Enables and disables the audible beep when
the meter's pushbuttons are pressed.
Q. Erase all memory:
Erases all stored measurement
transactions saved in the meter's memory.
