A. Introduction
ZT100 is a battery-powered, auto-ranging digital multimeter with a 4000 counts,
LCD display and backlight. It can be used to measure AC/DC voltage, AC/DC current,
resistance, capacitance, frequency, duty cycle, diode, and continuity.
B. Safety Information
To avoid possible electrical shock, fire, or personal injury, please read all safety
information before you use the product.
(1) Do
NOT
exceed the “
maximum value
” indicated in the Specification.
(2) Examine the connection of the test leads and the insulation of the product
before measuring voltage higher than 36V DC or 25V AC.
(3) Disconnect the test leads from the circuit before changing the mode
。
(4) Misuse of mode or range can lead to hazards, be cautious. “OL” will be shown
on the display when the input is out of range.

button and you will see “HOLD” on the display;
press again to cancel. To turn on the backlight,
press this botton for more than 2 seconds;
long-press again to turn off.

measurements.
5. COM: Common terminal for all measurements.
6. 10A: Input terminal for current (A) measurements.
(2) Measure AC/DC Current
1. Connect the black test lead to the COM Terminal and connect the red test lead
to the VΩHz Terminal or the 10A Terminal (choose based on the value of
current) ;
2. Turn the rotary switch to the Current-A Mode or the Current-mA Mode;
3. Press SELECT to toggle between AC/DC;
4. Break the circuit path to be measured. Then connect the test leads across the
break and apply power;
5. Read the measured current on the display.
*Caution:
a. Do not measure current that exceeds the MAX Value as indicated in the
Specifications;
b. Use the 10A Terminal and the Current-A Mode when you are measureing an
unknown current. Then switch to the VΩHz Termianl and the Current-mA Mode if
necessary.
Do not input voltage exceeds 36V DC or 25V AC when you are at the
setting of measuring current.
