1. IMPORTANT SAFETY INSTRUCTIONS
1.Do not use this apparatus near water.
2.Clean only with dry cloth.
3.Do not block any ventilation openings.
4.Do not install unit near any heat source or heating emitting devices.
5.Prevent the power cord from being walked on or pinched.
6.Unplug this unit during lightning storms or when unused for long periods of time.
PRECAUTIONS
1.The unit must be used within its specified range.
The rated input voltages can be found on the rating label at the back of the unit. Before plugging into the AC supply, check with the rating label.
2.This unit has a built-in Tracking O.V.P. (Over Voltage Protection) feature. In the event of the output voltage becoming 10% greater than the set value, the O.V.P. wi11 be triggered and the output power will be cut off and > FAULT< warning will appear.
When you get this warning, switch off the unit and remove all loading.
If you switch the unit back on again it should resume normal operation. In the event that this problem persists contact the manufacturer.
3.This unit has a buzzer built inside. The buzzer will sound when Over Temperature/Overload/Over Voltage Protection has been triggered. When you get this warning, switch off the unit and remove all loading.
Check your load and output voltage setting. Allow the unit to cool down for 30 minutes.
If you switch the unit back on again, it should resume normal operation.
In the event this problem persists, the unit must be investigated by your agent.
4.Only use the supplied software and optional accessories with this unit.
5.Refer all servicing to manufacturer.
Warning!
The maximum output voltage for Model 1698 is up to 60Vdc.
It may be hazardous to touch metal part of the terminals.

3. INTRODUCTION
This series of laboratory grade, switching mode, programmable power supplies are ideal for repetitive test routines in R&D, Production, Product Evaluation and various applications.
Information appearing on the large back-lit LCD makes the panel controls simple and easy to use in spite of its sophisticated features. Because of the MCU (Micro-Controller Unit) and the related software, user re-calibration without opening the case is an added bonus.
When used with a standard PC, the supplied user friendly software and built in RS-232 interface provides two way communications improving the functionality of these units.
Data logging with color graphic display in adjusting range Voltage, Current, Watts, and time periods are all valuable tools in data analysis. Please keep this manual in a safe place and contact the manufacturer for any special requirements in application software or other features.

5. GENERAL OPERATION PRINCIPLE
Therearefouroperationmethodsforthisunit:
•Manual Operation
•Presets
•Timed Program
•PC InterfaceMode.
The large Liquid Crystal Displaywill guide you through the various operations/procedures interactivelyonce you understandthe operationprinciple.
There arefour Dual Function Control Keys |
for various operation modes andinput states of the unit. |
To change/set operation mode (output on /off, key lock &etc.), inmost cases you need two Dual Function keys tocomplete the operation.
To change input values of various settings (voltage, current, preset number, cycles, time period &etc.), usethe ENTERkeyto get readyand confirm the newsettings.
Liquid Crystal Display
The back-lit displayshows boththepreset andthe actual voltage, current levels at the output terminals; andstatus of constantcurrent (CC) or constant voltage(CV) mode. Be aware of new symbols appearing onthe displaywhileinputting. Theywill guide you and remind you of the correct procedure.
Example: Inputting values of various settings
When a newsetting (voltage, current, time periods & etc.) is readyfor inputting, thesymbol for therelatedsetting will appear on the display. After you keyin the required value, always follow bypressing ENTERtoconfirm or tocompletethe operation.
Presets and TimedSubprograms
This unit has thecapacityto store10 programs.
8
Program 1 to9 is for nine sets of Presets of voltageandcurrent.
