1. Safety information
◆ The ST-HDoC/ ST-HDoC-MM is intended for use in compliance with applicable codes and
laws.
◆ Do not expose to moisture.
◆ Do not drop.
◆ The tester should not be charged over 8 hours.
◆ The tester should not be used in an environment with any flammable gas or chemicals.
◆ Do not disassemble the tester except to change the battery.
◆ Don’t use any chemical cleaning products to clean the test meter. Use a dry cloth.
1.1 Digital Multi-meter Safety
◆ Prior to taking any measurements, be sure you are using the correct range, function and input
jack. Red is positive, black is negative.
◆ Never exceed the protection limit value for each range of measurement.
◆ While measuring a live circuit, do not touch any unused terminals.
◆ If the value to be measured is unknown while using the manual range, set the range selector to
the highest position.
◆ Always be careful when working with AC or DC voltages since you could be injured or killed
by voltage going through your body. Keep your fingers behind the probe barriers while
measuring. Do not touch the metal probes while taking any measurements.
◆ Never perform any capacitance measurements unless the capacitor has been fully discharged.

2.3 Function
2.3.1 Video signal test
The new ST-HDoC tester with 3.5 inch LCD-TFT, 480（RGB）x320 resolution, allows the user to view
the images from sufficient angles. The display is suitable for outdoor installation and maintenance
work.
2.3.2 Video level meter (CVBS)
Performs NTSC and PAL video amplitude signal measurements for PEAK to PEAK, SYNC level,
COLOR BURST, and CHROMA level
Video signal PEAK to PEAK level:
For NTSC format, the video signal level is 140±15IRE
For PAL format, the video signal level is 1000±200mV
If the level is too low, it will cause the image to lose quality and limit the distance it will travel over a
coaxial cable. If the level is too high, it will lead to a washed out image.
SYNC level: Testing the amplitude of the video sync pulse to verify if the video level is correct.
For NTSC format, the SYNC level is 40 ± 5IRE
For PAL format, the SYNC level is 300 ± 35mV
If the level is too low, it will cause the image to not frame out properly. If the level is too high, it will
lead to poor video quality.
3
ST-HDoC / ST-HDoC-MM
COLOR BURST level: Testing the color burst level will determine if the burst signal is sufficient to
trigger the displays color producing circuit. Burst will diminish in amplitude over longer cable runs and
can fall below the threshold for the video display to show a color image.
For NTSC format, the chroma standard level is 40 IRE
For PAL format, the chroma standard level is 280mV
If the chroma level is too low, the color will not be as deep, and some details of the image will get
washed out. If the chroma level is too high, there may be spots on the image. If the coaxial cable is too
long, it will reduce the chroma level.
2.3.3 PTZ controller
Displays and allows for analysis of analog video and controls pan/tilt/zoom functions of an analog PTZ
camera. For PTZ testing, setup the controlling parameters from the meter to match those of the camera:
e.g. PTZ protocol (PELCO-D, etc.), communication port (RS-485, etc.), baud rate, PTZ camera ID and
pan/tilt speed.
2.3.4 Enhanced Color bar generator
The newly added gray-scale image test, allows the tester to test the monitor for optimal gray-scale
performance. The tester sends out color bars via its BNC output to the monitor. This is used to test for a
problem in the cable going from the camera back to the monitoring area
2.3.5 DC12V 1A output power
The unit can power a camera with 12V DC (1A) power output from the tester. It is helpful for
determining powerline issues or if power supply box is malfunctioning.
2.3.6 Audio testing
Test the audio input from pickup devices. Connect the tester and pickup device with the audio cable.
Consult your local laws and regulations on recording audio and using audio devices. In the
United States of America and all individual states thereof, there are federal and state laws that
limit your ability to monitor and / or record audio. These laws expose you to the risk of criminal
prosecution and potentially give an injured party a civil claim for money damages against you.
2.3.7 Cable tester
Connect a LAN cable from the ST-HDoC/MM unit to the included blue remote cable tester. The unit
will test for connection status, cable type and the status of each wires conductivity will be displayed.
4
ST-HDoC / ST-HDoC-MM
2.3.8 PTZ controller
Test the PTZ control command data to diagnose any errors or to ensure there is a sufficient
RS485/RS232 data transmission. The unit receives the control protocol code (PELCO-D, etc.) from a
PTZ keyboard or a DVR with a RS485/RS232 interface.
The unit will display 16 hexadecimal codes such as:
PELCO-P：A0 00（Add） xx xxxxxx AF xx
PELCO-D：FF 01（Add）xx xxxxxxxx
2.3.9 PTZ address scanning
Search the ID/ Protocol/ Baudrate of a PTZ camera being tested.

video signal level.
If the coaxial cable is too long, it will reduce the video signal level. If the level is too low, the image
will not be as deep and its dynamic range will be reduced. If the level is too high, the image will
get washed out. There will be prompts that appear on screen if the level out of range.
18
ST-HDoC / ST-HDoC-MM
Depending on the type of camera connected to the ST-HDoC, the Video “Format ” will automatically
