Manual range selection
•
After entering the R function measuring range is chosen automatically.
•
If necessary, you can press and release the
RANGE
key to select a certain
range, thus disable and eventually re-enable auto-ranging.
Important notices for resistance measurement
-
Do not connect test tips to external voltage
in the R function. Such status is
indicated by beeper and the symbol "Uin", but despite it the instrument can be
damaged!
- Measurement of low resistance with 200 mA current heavily loads the supply
accumulators /batteries of the instrument.
Carry out resistance measurement
only for necessary period of time
. If you see a low battery indicator or if there
are other problems, for example spontaneous shutdown of the instrument,
display flickers, malfunction of control keys etc., insert new fully charged NiMH
batteries, or the quality alkaline batteries. See chapter 4.1 for instructions how to
do it.
3.3.3. Function "●›)" - beeper
The „●›)“ function is intended for measurement of resistance in range 0 - 4 Ω. If
measured value is between 0 - 4 Ω, it is signalized by beeper. Follow the same
measuring procedure and consider the same warnings that are stated for the
resistance function R (see chapter 3.3.2.).
3.4. Phase (live) conductor test, phase sequence test, DIGISORT
Repeatedly press and release the
FUNC
key to select between the following
measurement functions:
3.4.1. Single-pole / contactless phase indication
This function is suitable for contactless indication of the presence of voltage on
conductor / device and contact single-pole indication of the phase conductor.
•
Press and release the
FUNC
key to select the phase indication function. The
right side of the display briefly displays bar graph "-------------" and the left side
displays "X" on a blue field.
•
Approaching the test tip on the instrument’s case to the conductor / device
under voltage bar graph indicates the growing intensity of the electric field.
•
Sensitivity can be switched in two steps by the
RANGE
key.
•
Acoustic signalization can be switched on / off by the
CAL / ELEC
key
•
Touching the test tip on the instrument’s case to the measured conductor with
voltage ≥ 190 V / 48 ÷ 52 Hz against the earth, the "L" symbol is displayed on
the left side of the display.
